We accept that human drivers are not perfect and are going to cause thousands of deaths per year with their vehicles. It's a whole different ballgame to accept that computers are going to choose to kill thousands of people per year, and it is not much comfort to know that it's slightly fewer thousands of people. I think this is especially true when the response to such deaths is not "we will investigate thoroughly and ensure this never happens again". This is not a logically consistent argument, but humans are not logically consistent beings.
