There was a time back when gas prices got kinda high when I thought Americans would finally shift down to slightly smaller cars, but now it's practically a cultural thing for half the country to burn as much fuel as possible, so I suspect even if gas prices here hit Europe levels it wouldn't cause them to budge much.
It does feel really odd, though, going somewhere like a school and just being absolutely surrounded by huge SUVs and pickup trucks that you know damn well like 90% of the drivers aren't actually utilizing.
Double-sucks because it's becoming more and more difficult to find a small car. Everything new, even most cars, are huge.
Looks to me like vehicle sales have been taking dramatically, probably due to the increased cost due to "supply chain". Also, EV sales grew 42.7% last year.
