The higher numbers of traffic fatalities in the US aren't simply because Americans drive further- American roads are more dangerous per billion vehicle km than roads in other developed countries.
I wonder what would happen if you normalized by SAT/ACT score (or something that stands in for education level).
Places like Germany can afford to prevent anyone from getting a vehicle that isn’t capable because of public transportation.
If you prevent a rural American from driving, that is a wholly different situation.
Drive less, train more, stop buying huge SUVs, improve traffic laws…there’s a lot we could be doing.
