True, and that's a fair way to look at things. To me, the overall picture is that young men are exceptionally self-destructive when compared to anyone else.
While self driving cars are part of the picture towards reducing deaths in this group, it's incomplete; and you might do just as well with better parental controls and driver behavior reporting embedded into vehicle control software. Some of this is already available, but I have a feeling it's used far less often than it otherwise could be; which speaks to differing levels of parental involvement in the safety of their teenagers.
At the same time nobody's discussing taking motorcycles off the road and we're not at a point where we can put the requisite technologies in motorcycles to grant them the same safety we're supposing automated vehicles will possess. These vehicles in particular kill a disproportionate amount of young males.
Even if we do add these technologies to a motorcycle, you can still buy an ATV, or a snowmobile, or a farm tractor or any number of other off-road gasoline powered gadgets that can quickly become lethal.
I have nothing against the advancement of the safety of human society through technology, but I don't like the taste of the automated vehicle kool-aid that gets passed around and I'd like us to hedge our bets. That's all.
