Gerrymandering, old-politics, fairer versions could be worse than less fair

Leave a reply

There is no truly good way to give representative voices to a population. The founders of the country decided that there would be a set number of congresional representatives, divided it by states, and left it to the individual states to subdivide, with a few provisos. They mandated that congressional districts have to be contiguous, entirely within a state, and contain approximately the same number of citizens in each. A later law specified that the districts should not directly disadvantage a racial minority. Within these parameters, legislators in most states have divided congressional districts to advantage those in power to a greater or lesser extent. The most egregious of these are Gerrymanders, odd shaped districts that protect sitting congressmen and parties, as bad as the worst of these are, they are better than some, truly awful, “fair” divisions, in my opinion.

This was Michigan’s district map (Detroit area) until redrawn by independent commission, 2022. My district was the dark blue one that looked like a man in a chair.

Consider my state: Michigan, a swing state that voted for both Biden, and Trump. Currently the state house is 52% R and 48% D, but Democrats were in majority as recently as 2024. Our congressional district map used to be a disaster, shown at left. In 2022 it was replaced by a map created by an independent committee that aimed for roughly square districts that aimed to keep towns and communities together. The result is that most districts are either safe D or safe R. This, we’re told, is bad in that it leads to factionalism, with congressmen pandering to political extremes, with little incentive to compromise.

A fairer alternative (?) would divide the congressional districts so that all or most district are swing, like the state. Supposedly such districts would elect moderates who compromise. This version, though no-less fair than the above, is not good, in my opinion. I expect it creates chaos and turnover. I’m also not convinced that compromise is always best.

Pennsylvania’s congressional map before redistricting by independent committee. Ugly, but fair in its way.

The variant of this that preceded our current is for congressmen and others in power to create districts that are fairly safe for themselves and their party, leaving those of the other party in a few, super-concentrated districts. This division is less fair, but far more stable and workable. It lead to ugly gerrymander districts in Michigan (left) and Pennsylvania (below). This is not bad in itself. What was bad about these gerrymanders is that the congress folk, secure in their jobs, formed a political aristocracy. Seats passed from generation to generation, and ruled fairly disconnected from the wishes of those they represented. A good part of the aristocracy is that they worked well with each other, across party lines. They were friends, alumni of the same schools, members of the same churches and country clubs. They were good-‘ol-boys, who didn’t pander nor embrace ideological extremes. Writers romanticize this, but I’ prefer our current’m glad it’s going in MI.

California and Texas politicians are pushing for more gerrymandering. California’s congressional districts were drawn by independent committee. Their governor called the Trump White House fascists as recently as today. There’s a vote to get five more D-districts. The claim is it’s to balance Texas’s push for three more R-districts. I nothing illegal or immoral here, just old style politics, power grabs left and right, with incendiary language. The districts look bad, but I’ve seen worse. No need to call ‘fascist’ unless your next step is to impeach president Trump again, or your hope is another shooting.

The worst option, in my opinion is term limits. It’s promoted from both sides, and I consider it insane, except for party bosses. It actively prevents people from re-electing the politicians they like based on the objection that these people have been on the job long enough to feel at home and get things done. I consider term limits completely non-republican, non-democratic, a disease, “fair” only in that it hurts every citizen equally, benefitting only party bosses.

98% Certainty that Trump has reduced crime in DC

1 Reply

It’s been 24 days since Trump sent the national guard into DC, and the crime rate has dropped by a factor of six. The murder rate went from 101 murders per year in 2024, one murder every 3.6 days, to one murder in 24 days. I find that the odds of this being coincidence is less than 2%. Car theft and other crime has dropped as well. I consider murder rate the best metric for crime because no murders go unreported, and none get misclassified as altercations or misunderstandings.

Using the National Guard to maintain order is not that unusual. Eisenhower sent them to Arkansas in opposition to the governor to ensure desegregation. LBJ sent them to Chicago to protect the Democratic convention of 1968.

To figure the odds that this improvement is coincidence, consider that the odds of a murder on any one day is 101/365 = .277. Based on this, the odds of no murder on any of particular days is, 1-.277 = .723. On any given day in DC it’s more likely to have no murders than to have a murder, but the odds get much lower for going many days without a murder, or for 24 days with only one. The chance of of having 24 days without murder, for example beginning at some set-start, would be (.773)24 = .0021 = 0.21%. The odds of having only one murder in this time is calculated similarly, as 24(.277)(.773)23 = 1.8%. This is to say that there is a 98.2% chance that the drop in crime rate is not accidental.

The D.C. Mayor Muriel Bowser had originally objected to the guard, but now is happy, or so Trump claims. If she removed them now on, she would have to argue that high crime rates are good. Other mayors may not want to be in this position.

A federal judge, Charles Breyer, just declared the use of the national guard illegal, by the way, a violation of the Posse Comitatus act of 1878 see the complete statement here. The Posse Comitatus act bars the use of federal troops for police activities, except federally related ones. Judge Breyer, decides that there is no federal justification and demands that the national guard leave within 10 days. Trump claims that various riots in DC and LA (and Chicago) constitute an insurrection, and adds that attacks on federal ICE agents and federal buildings makes it federal. Judge Breyer recognizes that many other presidents have used the guard for law and order, even in opposition to the governor. Eisenhower for example, or LBJ to protect the Democratic National Convention 1968, but sees no justification, here or (it seems) for Eisenhower or LBJ either. Judge Breyer seems to believe they all acted illegally. I don’t know enough law to judge, but recognize that allowing Trump to reduce the crime rate makes mayors and governors look bad. Detroit crime is awful, as is LAs, Chicago’s…

Tariffs on German cars are inflationary, but not for you.

1 Reply

As things stand, the major export of Germany to the US is high end cars: Mercedes, Audis, Porsches, BMWs, $100,000+ on average. The lower end models are made in the US, Mexico, and Canada. These high end cars are the biggest profit centers of their makers and of the German economy. Currently, they face an import tax (tariff) of 15%, the same as everything from Germany (or Italy or Japan). Liberal economists are furious at this; they claim it’s a tax and that it is inflationary. They are right on both counts except that this is only a tax and inflationary for the few Americans who buy new, high end cars.

The Americans who buy such cars are typically rich folks — poor and middle class folks can’t afford them. They are also folks with ‘taste’, folks who need a BMW, and would not be caught dead behind the wheel of a US car. Normally liberal economists would favor taxing such people, but these are often the who hire economists. They run the TV programs and newspapers, universities and hedge funds. They choose the economists and the economists are eager to see things their way.

Another high tariff item imported from Europe is art. Modern art for $1 million dollars that ends up in museums. For the average Americans the tariff on this, or on art is irrelevant or beneficial. The income it generates is used to offset other taxes, allowing Trump to remove the tax on tips, for example. That this tariff falls on rich people and replaces a tax that otherwise fell on poor workers. Liberal economists should favor of this, but their opinions are not their own.

A side benefit of these tariffs for ordinary folks, is that that they cause some buyers to switch to American-made products, cars and art. Perhaps not for themselves, but for for their children. They may buy a German car made in the US, rather than one made in Germany, or art from an American. This provides jobs for US workers — and an opportunity for Detroit to retool for the future. Detroit auto workers seem to understand this; they voted for Trump in 2016 and 2024. Detroit’s union leaders opposed tariffs. In Michigan, the union leaders get their power mostly from MI politicians, Democrats, who force union membership.

This is not to ignore the suffering of those who buy foreign products, the buyers of new BMWs, or French cheese, or high end art. As things stand, Columbian coffee is tariffed at 10%, and that may add 50¢/lb. Mexican coffee is not taxed, but many average Americans prefer Columbian. I hope they can be consoled by Trump’s tax breaks.

Some months ago, Trump showed off a tariff schedule that he considered ideal, with rates targeted to reduce our trade deficit by half. I derive here, Trump’s formula and rates, and give my opinions of the target. By the formula he presented, the EU tariff should be higher than it is, 20%. Trump has it at 15%, I think, for diplomatic leverage, to goad the EU into lowering their tariffs on us goods, now 15%. He’s also pushed them to spend more on defense, and pushed to end the war between Cambodia and Thailand. He threatened them with near 100% tariffs if they didn’t stop fighting.

Robert Buxbaum, September 2, 2025. Here’s a Bob Dylan song, union sundown, making a musical case against free trade. Once upon a time that was a liberal view. Now not. The NY appeals court ruled to block Trump’s tariffs to stop the horrible damage being done. My guess is the judges drink high-end coffee, eat French cheese, and drive new, German cars.

Pirates of the Bermuda Triangle.

Leave a reply

The Bermuda Triangle is a mysterious area of the Caribbean that has managed to swallow ships, and airplanes without a trace. Boats and planes go in fully crewed, and show up weeks later, empty. It’s a running mystery that has spanned centuries, and I think I have an explanation; pirates.

One clue supporting my explanation is that there were spurts of Triangle disappearances: the 1920s were very big, as were the early 1700s as were the 1980s. These were all times of major smuggling, and the area of the Bermuda Triangle is a haven for smuggling too. The 1920s was a time of prohibition and thus of peak whiskey smuggling between the US between foreign ports. Liquor was legal in Bermuda and Cuba. It was a short hop to Miami. My theory is that this smuggling attracted pirates, as any smuggler that was boarded was unlikely to contact the coast guard for protection. Sometimes the pirates killed the crew and took the illegal goods, leaving the rest. The manifest showed noting unusual because the illegal liquor wasn’t in the manifest. Another similar theory, is that the crew might become pirates themselves, mutinying.

A fairly typical case: In 1921: January 31, the  Carroll A. Deering, a five-masted schooner, Captained by W. B. Wormell, left Barbados, then vanished. It was found January 28, aground and abandoned at Diamond Shoals, near Cape Hatteras, North Carolina. Some background: The First Mate McLellan got drunk in town and complained to Captain Hugh Norton of Snow that he could not discipline the crew without Wormell interfering, and that he had to do all the navigation owing to Wormell’s poor eyesight.[5] Later, Captain Norton, his first mate, and another captain were in the Continental Café and heard McLellan say, “I’ll get the captain before we get to Norfolk, I will.”[5] McLellan was arrested in a drunken state, but on January 9 Wormell forgave him, bailed him out of jail, and set sail for Hampton Roads.[6] It was found without the crew, without the two lifeboats, and without much of the crew personal items. My theory is mutiny, the demons who did this were human, IMHO.

Check the screws on your door locks.

Leave a reply
Original hardware brass screws from my door and locks, plus one of the stainless screw that I used as a replacement.

I just replaced the door knob assembly on my home and found that it was held in place by a faceplate that was attached by two, 5/8″, brass screws. These screws, shown at right with their replacement, would not have been able to withstand a criminal, I think. Our door is metal, foam filled, and reasonably strong. I figure it would have withstood a beating, but the brass screws would not, especially since only 1/4″ of the screw is designed to catch foam. Look closely at the screws, and you will see there are two sizes of pitch, each 1/4 long. Only the last 1/4″ looks like it was ever engaged. The top 1/4″ may have been designed to catch metal, but the holes in the door were not tapped to match. The bottom 1/4″ held everything. Even without a criminal attack, the screw at right was bent and beginning to go.

Instead of reusing these awful screws or buying similar ones, I replaced them with stainless screws, 1 3/4″ long, like the one shown in the picture above. But then I had a thought — what were the other locks on my door attached with? I checked and found my deadbolt lock was held in by two of the same type of sorry, 5/8″ brass screws. So I replaced these too, using two more, 1.75″ stainless steel. Then, in my disgust, I thought to write this post. Perhaps the screws holding your door hardware is as lousy as was holding mine. Take a look.

This is not the most important election, 1860 was

Leave a reply

Every year we hear the same claim: that this the most important election of America’s history. This year is among the more contentious than most, but the issues dividing the candidates are few. Both, for example, claim they will protect the border and spur the economy. In lieu of issues, there’s name calling. Trump claims Harris is as incompetent buffoon and Harris claims Trump is a fascist dictator. The rancor practically guarantees as they’ll be riots whoever wins but, as these things go, the election is less important, and divisive than ’64 and ’68, and in particular, the election of 1860.

Following the 1860 election, election seven states ceded from the union and we had a Civil War. Even the most bleak prediction for 2024-25 is for a more peaceful transfer of power. The election of 1860 had two major issues on the ballot; one was slavery or rather the expansion of slavery to the territories, and the other was implementation of the Morrill tariffs. These import taxes, proposed by Justin Morrill and passed but not yet implemented, would have raised the average agricultural duty from 15% to to 47%. Duties on durable goods wool rise to 65%, with the burden falling disproportionately on the southern states. Duties on durable goods. There was also a price schedule that would have prevented British shippers from minimizing the effect by falsely claiming a price far below market, something China currently does. In September 1860, Republican Leader Thaddeus Stevens told a New York City audience that “the Tariff would impoverish the southern and western states, but that was essential for advancing national greatness and the prosperity of industrial workers.”

Matching the two sides to the two major issues of the day, there were four major candidates for president in 1860. All of them won states. Lincoln carried the greatest number, 18, and won the most electoral votes, 180. He was for high tariffs and against the expansion of slavery. Second was John Breckinridge, the Southern Democrat, who carried 11 states and got 72 electoral votes. He was for the expansion of slavery and against the higher tariffs. Then there was Stephen Douglas, the Northern Democrat, who was for allowing the expansion of slavery, considering it a “states right,” and also for the higher tariffs. Douglas carried only one state, Missouri, with 12 electoral votes. Finally, there was John Bell, the Constitutional Union candidate, who carried three states, Virginia, Tennessee, and Kentucky, representing 39 electoral votes. He opposed the expansion of slavery and also the increased tariff, but he generally believed that compromise was always possible. This was the worst vote split in US history. The worst split I’ve seen was 1968, when three candidates carried states.

Had either Bell or Douglas won, I suspect that the Civil War could have been avoided, at least temporarily. Virginia, the most important of the slave states, had shown it was willing to accept an anti-slavery president so long as he did not impose high tariffs — tariffs that benefitted the northern industrial workers and manufacturers at the expense of southern consumers and agricultural producers. Lincoln’s victory precipitated the immediate secession of 3 states. Another 4 seceded after inauguration.

The south imagined they could walk away because that’s how they read the constitution before the 13th amendment. They imagined they could win a civil war because they imagined they had British military support. “Cotton was king,” they claimed. The UK prime minister, Lord Palmerston, had told secretary Adams, “We do not like slavery, but we want cotton, and we dislike very much your Morrill tariff.” As it was, the British stayed on the sidelines, in part because of diplomacy. Besides, the gunship Monitor showed that the North could sink most any British ship that entered US waters.

As for 2024, I expect there will be riots whoever wins, but nothing more. The parties are realigning significantly, as happened in 1964-68, and neither side much understands the appeal of the other. This seems like less of a wrenching election than in 1964 and 1968, though. In ’64-’68 US boys were dying in Vietnam in numbers, and black folks and their white friends were being lynched in the south. Nothing like that is happening today. Today’s riots have been fueled by nothing more than name-calling, fear, and the occasional assassination attempt. Mild, even compared to 1968.

Robert Buxbaum, November 4, 2024. Justin Morrill is mostly remembered today for the Land-grant college act of 1862. This created an agricultural -technical college in each state. I taught at Michigan State University, Michigan’s land grant university. I’m generally a fan of tariffs, both as an aid to the domestic economy and as a tool of foreign policy. I present these views here. I got these views from Peter Cooper.

Sailors, boaters, and motor sailing at the hull speed.

Leave a reply

I’ve gone sailing a few times this summer, and once again was struck by the great difference between sailing and boating, as well as by the mystery of the hull speed.

Sailors are distinct from boaters in that they power their boats by sails in the wind. Sailing turns out to be a fairly pleasant way to spend an afternoon. At least as I did it, it was social, pleasant, and not much work, but the speeds were depressingly slow. I went on two boats (neither were my own), each roughly 20 feet long, with winds running about 10-15 knots (about 13 mph). We travelled at about 3 knots, about 3.5 mph. That’s walking speed. At that speed it would take about 7 hours to cross Lake St. Clair (25 miles wide). To go across and back would take a full day.

Based on the length of the boats, they should have been able to go a lot faster, at about 5.8 knots (6 mph). This target speed is called the hull speed; it’s the speed where the wave caused by the bow provides a resonance at the back of the boat giving it a slight surfing action, see drawing.

This speed can be calculated from the relationship between wave speed and wavelength, so that Vhull = √gλ/2π where g is the gravitational constant and λ is the water line length of the boat. For Vhull in knots, it’s calculated as the square-root of the length in feet, multiplied by 1.34. For a 20 foot boat, then,

Hull speed, 20′ = 1.34 √20 = 1.34 x 4.5 = 6.03 knots.

While power boats routinely go much faster than this, as do racing skulls and Americas cup sailboats, most normal sailboats are designed for this speed. One advantage is that it leads to a relatively comfortable ride. There is just enough ballast and sail so that the boat runs out of wind at this speed while tipping no more than 15°. Sailors claim there is a big increase in drag at this speed, but a look at the drag profile of some ocean kayaks (12 to 18 feet, see below) shows only a very slight increase around this magical speed. More important is weight; the lowest drag in the figure below is found for the shortest kyack that is also the lightest. I suspect that the sailboats I was on could have gone at 6 knots or faster, even with our current wind, if we’d unrolled the spinnaker, and used a ‘screecher’ (a very large jib), and hung over the edge to keep the boat upright. But the owner chose to travel in relative comfort, and the result is that we had a pleasant afternoon going nowhere.

Data from Vaclav Stejskal of “oneoceankyacks.com”

And this brings me to my problem with power boating. Th boats are about the same length as the sailboats I was in, and the weight is similar too. You travel a lot faster, 20 to 25 knots, and you get somewhere, but the boats smell, and provide a jarring ride, and I felt they burn gas too fast for my comfort. The boats exceed hull speed and hydroplane, somewhat. That is, they ride up one wave, fly a bit, and crash down the other side, sending annoying wakes to the sailboaters. We crossed lake St. Clair and rode a way down the Detroit river. This was nice, but it left me thinking there was room for power -assisted sailing at an intermediate speed, power sailing.

Both sailboats I was on had outboard motors, 3 hp, as it happened, and both moved nicely at 1 hp into and out of the harbor, even without the sail up. Some simple calculations suggest that, with I could power a 15 to 20 foot sailboat or canoe at a decent speed – hull speed – by use of a small sail and an electric motor drawing less than 1 hp, ~400 W, powered by one or two car batteries.

Consider the drag for the largest, heaviest kayak in the chart a move, the Cape Ann Double, going at 6.5 knots. At 6 knots, the resistance is seen to be 15 lbs. To calculate the power demand, convert this speed to 10 fps and multiply by the force:

Power for 6 knot cruising = 10 fps x 15 lbs = 150 ft lbs/s = 202 W or 0.27 hp.

Outboard motors are not 100% efficient, so let’s assume that you need to draw more like 250 W at the motor, and you will need to add power by a sail. How big a battery is needed for the 250 W? I’ll aim for powering a 4 hour trip, and find the battery size by multiplying the 250 W by 4 hours: that’s 1250 Hrs, or 1.25 kWh. A regular, lithium car battery is all that’s needed. In terms of the sail, I’m inclined to get really invovative, and use a Flettner sail, as discussed here.

It seems to me that adding this would be a really fun way to sail. I’d expect to be able to go somewhere, without the smell, or the cost, or being jarred to badly. Now, all I need is a good outboard motor, and a willing companion to try this with.

We’re depressed, allergic, overweight, alone, and demented. What causes what?

1 Reply

Among the wonders of the western world is how many people are allergic to nuts compared to a few decades ago, and to gluten, and to a host of other things that hardly anyone was allergic to 50 years ago. Perhaps it’s a change in perception, but it doesn’t seem that way.

When I was in public school in NY, back in the 1960s, there was a subsidized lunch program serving, every day, peanut butter sandwiches. Peanut butter is nearly totally fat. It was ladled each day, from a giant tub, provided by the USDA, and slathered on USDA bread along with jelly from some other vat. The smell filled the lunch area, and the fats and sugars filled our stomaches. No one seemed bothered by the nuts, and no one showed obvious signs of passing out. And despite the ill diet, we were less obeease than today. Even today, in poor countries, thy still serve massive peanut butter dishes, or bread covered in lard, and these countries show fewer allergy problems, and less obesity in general.

Perhaps it is the lack of exposure to peanuts in the US that caused the allergy (sounds almost plausible), and maybe it’s the dietetic food that causes obesity, and the glut of non-gluten that causes gluten allergies. These connections may be false, but If true, it would suggest we’re in for many more problems.

Moving to depression and dementia. We’re seeing more and more of both, and at earlier ages. In our era, virtually everyone over 80 shows signs of clinical dementia, often Alzheimer’s dementia, but the rates are rising, especially in those 55-70, and it seems most every adult is depressed. I don’t know why, though lots of people on the internet have speculative explanations. There are also cures, and perhaps some work. The research behind at least one of the best hopes for an Alzheimers cure was shown to be falsified, just made up. Not that funding was stopped quite, highlighting another problem that is becoming more common: people in trust positions no longer behave in a trustworthy way. Nor are they punished for lying. Strange to add that an anti-obesity drug, Metformin, seems to actually work at weight loss, and helps against Alzheimers dementia. Then again, from other research, it seems that obesity protects from dementia.

Some of the problem seems to be societal, a lack of friendship and companionship. I could imagine that isolation leads to dementia, depression, and weight gain. Another thought, pushed by RFK Jr., is that new drugs and vaccines are responsible for allergies and ADHD, along with changes in diet. It’s possible. At least some comes from early diagnosis, and a change in the definition of dementia. Perhaps that’s the reason for the significant difference state to state. Yesterday’s curmudgeon is redefined as depressed, and drugged (more in some states than others), and becomes isolated (again more in some communities). The disoriented, lonely patient is then given anti anxiety drugs and classified as a dementia patient. It happens in some cases, but there seems to be a rise in real dementia too: the sort of stumbling and blankness that reflects general brain deterioration. As for ADHD, I’m still not convinced this is a new real disease; it could be that’s how boys always behaved.

Would we be less depressed or demented or less autistic with different vaccinations, or different foods, or with more human interaction? Would people be less isolated if they were less depressed or autistic? RFK’s family now claims that RFK Jr is demented himself for even asking these questions. My guess, totally unsupported is that the rise in allergies, dementia, obesity, and depression are related somehow, but I’m not convinced that RFK Jr. has picked out the right connection. What causes what? Perhaps someone can use statistics, or biology experiments to help untangle this stuff. It seems horribly important to the majority of Americans.

Robert Buxbaum, Sept 10, 2024. There was a. bit of a joke in the last comments: my daughter got a degree in epidemiology, and is employed in part to answer just the sort of questions I’ve posed.

Fewer serial killers, more mass shootings, blame unfriendliness not lax gun laws

Leave a reply

It’s hard to notice the lack of something, but there’s been a sharp drop-off in the the number of serial killers. Nearly gone are folks like John Wayne Gacy (the clown killer), Jeffrey Dahmer (severed heads, cannibalism, necrophilia), Gary Ridgway, “The Green River Killer” (71 prostitutes killed). Mostly, they were sexual sadists, men who’d have sex with strangers (able or female) and then kill them. In 1987, there were 198 active in the US and many more inactive; by 2018 it was down to 12. And these few are less-prolific, and less-colorful, like Anthony Robinson, “the shopping cart killer”, who killed 4-6 in DC, transporting the bodies in shopping carts.

It’s not clear why there are so few these days. Perhaps it’s the prevalence of surveillance cameras, or improvements in DNA and other pic technology. But these explanations don’t explain why there were so few before 1960. There were some mass murderers, “Jack the Ripper,” “the Boston Strangler” but few before 1960.

Police like to credit the drop off to their detective skills, but there are still plenty of violent crimes that go unsolved, about half the murders in Detroit for example, or most of the rapes in Europe. I suspect that serial killing spiked up in the 60s because of a spike in friendliness, and spiked down in the 2000s because it ended. Before the hippy era, people were cautious of gangsters, rapists, homosexuals, and spies under the bed. But that changed in the 60s. Folks thought it was cool to hitchhike, or pick up random guys. Now, we’re back to being cautious.

A personal story: I was visiting Toronto in the late 1980s and someone I didn’t know overheard that I was planning to drive back to Detroit that afternoon. He asked if I would not mind driving his teenaged daughters to Detroit to see their grandmother, and I said “yes.” At the border, the guards asked who these girls were, and I said I didn’t know. I hadn’t asked. The border guards let us through without passports after a call to the grandmother. I would not be as ready to offer a ride today, and the parents would not be as trusting, nor would the guards.

Serial killings are down since 1990, but mass shootings are up.

Despite much the stricter gun laws, there’s been a rise in crime and a steady growth in the number of murderers in our major cities. There’s also been a rise in synagogue attacks, and a rise in mass murders. These folks kill many in one day or as part of gang-drug activity. Stricter gun laws seem to have made things worse, not better. They do not stop the killers and they hamper the defenders. I took a look at synagogue attacks, and find a pistol would have helped.

On a societal level, I think it would help to have fewer illegal aliens, or aliens who enter with no positive record or skills. It would help to have psychological treatment and lockup for crazy folks and prisoners. Currently, we send violent crazy folks out on the streets until they do something true horrific. More consistent prison sentences are needed for criminals too. We’ now’ve come to use the courts for political theater: Biden’s son should not go to jail for years because he lied on a gun purchase, nor should Trump get for putting down a prostitute as “legal fees”. Nor is his half-billion dollar fine appropriate. Minor crime deserves minor punishment. As a result of our crazy courts, violent criminals are let go as with the MSU killings near me. He was a crazy violent black man, and there was no way, in the law to give him a short sentence, or counseling, or job training. When our incarcerated leave prison, they have anger, plus no jobs or skills. Don’t be surprised when these folks turn to violent crime.

7% of new US vehicles were EVs in 2023. Expect slow growth in 2024.

Leave a reply

About 7% of new US car and truck sales in 2023 were electric, 1.2 million vehicles. Of these, about 55% were Teslas. These numbers make sense based on US manufacturing and driving habits, so I don’t expect fast sales growth in 2024.

Currently home owners are the only major group of private drivers that save on fuel cost from owning an EVs. Home owners pay relatively little for electricity, about 11¢ per kWh, and they can generally charge their EVs conveniently, at home, overnight. Charging is more expensive and inconvenient for apartment dwellers. As a result, in 2023, some 95% of US EV sales went to home owners. Over 2 to 3 years they could hope to recover in gasoline savings the $7000 more that their EVs cost compared to petrol-powered vehicles, but they still have to drive a fair amount. A full charge of 80kWh EV at home will cost about $8.80 at current rates. This will power about 250 miles at a cost of 3.5¢/mile = $8.80/250.

Home, level 2 Chargers will cost about $1500 including the electrician cost.

The cost of gasoline is about 16.5¢/mile = $3.80/gal/ 23mi/gal) suggesting that you save 13¢ per mile by owning an EV. In order to recover the extra $7000 cost of the car in two years, you’d have to drive 27,000 miles per year, or 74 miles per day. To recover the difference in three years, you must drive 50 miles per day or 18,000 miles per year. This is more than most people drive.

EVs also offer reduced maintenance, but customers can balance this against the inconvenience of long charge times and spotty availability of chargers. My sense is that the fraction of Americans who benefit and drive 50-75 miles per day is about 7%. This fraction will increase as EVs get cheaper, but families that can benefit already own an EV.

The average Tesla costs today about $3000 more than the equivalent petrol car, but that still makes it relatively expensive, and it seems that the price differential was intentionally set to match sales to Tesla’s production capacity. Tesla could make EVs cheaper than petrol cars and still make a profit on each, but if they did this, they would have too much demand. Other US auto makers are mostly lose money on EVs and are unmotivated to lower prices. Based on this, my sense is that it is unlikely that sales will be much higher in 2024 than the 1.2 million sold in 2023.

The Chinese have plenty of new EVs, and they are eager to export. Their car market is currently about 50% EV, with companies like BYD selling EVs for as little as $12,000. The Chinese government subsidizes production and powers their EVs with cheap electricity by burning coal. These cars do not seem very good, compared to Tesla, but at this price they would flood the market if allowed to compete. The US government has kept them out with tariffs and with complaints about slave labor. Trump has promised a yet higher tariff, 100% on Chinese cars, if elected. The intent is to preserve US jobs and manufacturing. This is one of those situations where tariffs are good, IMHO.

Toyota Prius, the most popular hybrid.

Hybrids are a third option, cheaper than EVs, high mpg than normal engines. Though they are sometimes touted as a transition to EVs, to me they’ seem to suit a completely different demographic: those who don’t own their own home and drive a lot. Toyota makes the most popular hybrids in the US. They cost about $4000 more than the equivalent petrol car, $30,000 for a Prius vs $26,000 for a Corolla. When using a Prius in the city, you’ll get about 50 mpg, spending 7.5¢ per mile ($3.80/gal / 50 mpg = 7.5¢). This implies a gas savings of about 9¢ per mile vs an ordinary Corolla. Based on this, you have to drive about 27,000 miles per year in the city to recover the cost difference in two years. That’s a lot, and your performance is typically worse with a hybrid: you have a heavier car with a small engine. Maintenance cost is also higher with a hybrid than with an EV: you still need oil changes, fluid changes, belts, etc. and the mpg advantage vanishes on the highway. A hard driving home owner is better off with an EV, IMHO, an apartment dweller with a hybrid. Hybrids also should make sense for taxis and local-haul trucks. I can imagine hybrid sales rising in 2024, perhaps as high as 15% of vehicle sales. What we’re all waiting for is more near-shore manufacturing (or mandates), and this is not likely in 2024.
