The statistical fact that if every robotic car on the roads had been driven by a human, then there would have been ten fatal accidents in the time it took for this first robotic car fatality to happen isn't much comfort to the family of the hypothetical dead victim. Especially when the on-board cameras show that this particular accident would have been trivially prevented by a human driver. And you can bet that *some* politician is going to plaster that hypothetical victim's face all over the national news until everyone knows that robotic cars are a terrible idea and should be banned.
Now, we can hope that cooler heads would prevail, and the video of the avoidable crash would be shown along with dozens of videos of crashes that no human could have avoided. That people will point out that even if it does sometimes make mistakes, it's still better then a human driver, that injures and even deaths result from seatbelts and airbags, but that we keep them anyway because they save more lives then they take. That we can change the software so that this particular mistake never happens again, and do more testing to eliminate any other extant problems before anyone is hurt. Not to throw the baby out with the bathwater. We can *hope* for that, but I personally don't have enough faith in US politics to really believe it.
