I think this is where Sci/Eng meets the the Daily Mail.
It's perfectly logical and rational to introduce a technology that will reduce death figures overall even if that technology may cause some deaths. i.e. Introducing autonomous vehicles may save 1000 lives whilst costing 10.
990 more people is walking around is better, yes? Shame about those 10 but 990 is bigger than 10 and the needs of the many...yada....
Except when YOUR autonomous vehicle crashes into a bus stop killing 5 kids whilst avoiding the garbage dropped in the middle of the road that looks vaguely like a person to the car you'll see Daily Mail headlines of "Killer technology murders family, where will it end, the machines will murder us all".
Then the politicians will panic, pass knee jerk legislation and basically the autonomous vehicle 'thing; will get hobbled for 20yr.
Got to think of the bigger picture and the number don't always work outside the lab in the irrational meatware that will make decisions.
