It is supposedly a personal moral failing every time someone drives too old, too tired, or too impaired, but if trains, busses, & walking were the default ways to get around then this chronic societal problem would diminish dramatically. For the vast majority of US citizens busses, trains, walking, biking, etc are not viable options because US infrastructure & city planning overwhelmingly neglects everything but the automobile.
Incompetent driving is rooted in systemic failures, not personal moral ones.
