@maporsche,
This was probably avoidable. Most accidents are. For all we know, the guy behind the wheel might just have been distracted. And of course it happens to normal dudes driving normal cars too.
As I said before, driving has life and death consequences. It's far more complicated and potentially impactful that automated translation. It's hard to kill someone with the wrong prepositional phrase, far easier with a car. Computers are not smart enough to drive.
Note that automated cars could also be loaded with explosives and programmed to drive through a busy street and Ka-Boom. Or just be programmed to run over people... They're more of a hazard than a convenience, me think.
