Hello; There is a flaw in this logic. Something like it is ok if something we do not need to have around in the first place kills a few people as long as it kills fewer people that an equivalent human operator.And the ratio of passenger deaths in self-driving cars is overall much lower than human-driven cars.
I can see self-driving machines being used in a lot of places just not on a public road. Maybe after a long time when most of the kinks are worked out they may have a place on public roads. I think the companies pushing self-driving machines have something other than public safety in mind.
Here is an unrelated but in the same sort of ballpark example. I have recently been looking at new cars. I find some bothersome trends. One has been around a while. On my 2004 Silverado the headlights are automatic. I cannot turn the auto headlight feature off. Most of the time this is not a problem. I do however drive thru a tunnel very often. About a third of the way into the tunnel my headlights come on when the sensor is tripped. I know this aggravates other drivers because it bothers me when their headlights come on in my mirror. Not a major thing but still some thing the designers could not anticipate.
