content: This is the correct answer. The simple fact of the matter is that if we allow cars to do this sort of analysis, we're going to end up with everyone having their car's transponders set to identify them as a school bus, and the passenger counts will always be several hundred infants and orphans. Aside from the fact that my own inclination is to save myself, the right or wrong of the situation is completely irrelevant if you base it entirely on faulty data, and chances are the car isn't going to know any better how many people are actually in the car you're hurtling towards.  Your car will have one thing it has control over for certain - itself - and everything else is guesswork, estimates, or unknowns.  And I inherently distrust the idea of the cars communicating together to determine in a split second whether someone should be "voted off the island" permanently. Never mind the bugs, and the "bugs," that will arise from this. Also, IIRC they did a survey on this and basically what it suggested was that people wanted everyone to buy a car that goes for "the least lives lost," yet would always, for themselves, buy the car that saved their own ass.  edit: I don't understand why people bring up "conundrums" that have a clear answer if it was a person driving.  Because they gotta bring in eyeballs.
