You're not wrong. There are plenty of accidents caused by inattention and poor driving that aren't fatal, but that do result in injuries... a quick search didn't give me much information but crashes with injuries appear to be about 100x more common than fatal crashes. This doesn't take into account how serious the injuries are, however. So if we assume that serious injuries are 10x more common than fatalities, that raises the odds to one incident per 750 years, or 1 incident per 75 years of any accident at all. You're still talking about things that happen to people once or twice in their entire lives. Of course there will be outliers (I've been in 5 accidents myself, only 1 with injuries) but the odds of being in a crash don't seem to be worth the risk of trying to automate mousetraps... we should concentrate on replacing car-based transportation instead of trying to use magical black boxes to make it theoretically safer.
