Peltier stuff today is really inefficient. Like, even in a lab it only gets to 30% efficient.  Really not what you're looking for.

At any rate, laws really shouldn't be dictating technology anyway; they should be dictating outcomes. Only when the method to reach an outcome is egregiously hazardous to society should government be making policy about a particular method or tech.  Generally you don't even need to be specific; if you have a law "don't poison people" you shouldn't need laws "don't poison people with lead. don't poison people with arsenic. don't poison people with chemical X..."  sadly our legislation tends to do the latter instead of the former... makes it super complex and inefficient.

(wonder why EV sales tanked? The loss of the $7500 tax credit is a big factor... because effectively no manufacturer was eligible for it any more).

False assumption. EV sales hit a record level in Q2 2024, and every manufacturer except Tesla saw a significant boost in sales (meanwhile, ICE sales were down a few percent compared to the same time in 2023. Ford's struggling a bit, primarily because they went all-in on the higher-end market and it is the low-end buyers that seem to be most willing to embrace electric drive.

I think EV sales have recovered, but there was a dip right after the tax credit expired.  OEMs dropped their prices after that, too... so in the long run it evened out.

I totally agree that the OEMs making too-large, over-tech-heavy vehicles is not good for either ICE or EVs though.

I like that NHTSA is working on regulations to limit vehicle size. I don't like that NHTSA is mandating more built-in electronics though.
