That is largely due to built environments like parking lots and asphalt sidewalks

of course! its those damned sidewalks

yet people are killed / injured on european road at much smaller rate than in the US. the best US state is less safe than even the worst canadian province (and canada isnt even good). the US treats its roads like a car crash derby so it needs “higher standards”, but that approach is provably terrible. not only vehicules are huge and wasteful, but the roads remain horribly unsafe as well.
