The US car fatalities per mile is double than the UK. It would at least be useful to ask why that might be. That's 40,000 people a year who have their lives cut short.
Obligatory “almost nobody in the US chooses to drive” comment.
Driving in the US is a lifeline. It’s closer to food and shelter than a product or action. Remaining economically afloat in the US without a car is extraordinarily difficult. Many people, especially poor people, would much rather lose their job or health insurance than their car.
The only meaningful way to say is to compare it to other countries. Pr vehicle mile it is a lot more than many Western European countries and Canada, and a lot less than Mexico.
IMHO it kinda is. It's 13x as many people as died in 9/11
