It shouldn't be too difficult to think up a scenario for an impending collision where the autonomous car you are travelling in will sacrifice your life (or at least seriously injure you) rather than taking evasive action that would/could maim or kill others. Can you come up with one? Approaching a ...

Re: Safety systems are there to be gamed...

We know how fast pedestrians can move sideways (it's not an infinite speed) and have automatic cars moderate their speed when passing humans at that distance, such that any impact will not do significant harm (another calculable limit that we can stay well below).
