The overwhelming majority of mayhem on the roads is caused by the long tail of bad decisions made by humans who would be able to pass whatever dumb requirements you concoct. Kicking the elderly off the road, throwing the book at the one guy who gets caught doing NYC-DC and back in a day and onerous regulations on equipment is fundamentally a waste of resources chasing a long tail and is going to do nearly nothing to actually affect things relative to the expense. Most of the problems are caused by people doing things they knew were risky and stupid at the time and did them anyway, breaking rules in an irresponsible manner, distractions, intoxication, etc. Being applicable to a broad cross section of the actual problem is why low hanging fruit type stuff like AEB has such a big impact.
