Yea, depending on where you live in the USA, you practically need a car of some sort. Yes, there are cities where you can get away with not having one, but the vast majority of Americans would have to make a huge lifestyle sacrifice to not have a car. Some people need trucks to haul things, but NOBODY needs giant-grilled zero-visibility monster trucks or monster SUVs where you can't even see a person standing in front. You could get rid of these atrocities and not kill cars/trucks in general.

Maybe that's where effort should be focused.

Having any car or truck is a choice. People lived before the automobile. They do provide benefits, just as SUVs and trucks provide benefits. The Amish live without cars, so too could we if we chose to. In fact, the Amish could make the same claim about all automobiles that you make about preventable deaths attributed to larger vehicles.

I believe that you don't need one, and I know that I don't need one, but I think it's a little rich to make that a blanket statement for the species. There are people who have jobs, lives, and live in places unlike your own experiences.
