As a society, we seem unable and unwilling to deal with the carnage caused to drivers and, disproportionately, to pedestrians and cyclists, by the small minority of drivers who are:
Drunk (and drugged)
Distracted (cell phones, texting, smartphones, GPS, in-car entertainment systems, dashboard internet)
Deranged (boy racers, rage addicts, poisoned by testosterone, ego-maniacal, and those sad medically afflicted people)
Dumb -- unable to understand the complexities of driving.
All these are easily identifiable types, but as a society, we do very little about getting them out from behind the wheel.
And so we continue to kill tens of thousands of people per year this way, and injure millions. If this carnage were caused by, oh let's say, seagulls -- there would be squads of soldiers everywhere mowing them down with shotguns.
