The most important point is NOT a single car doing something, but what a flock of such cars can do once commanded from remote. We have already seen theoretical attacks against cities bricking few cars in strategic spot, trapping 99% of the traffic, attacks against electricity grid with spike loads or spike drops, individuals pushed to their death apparently by accidents or pushed toward others in an apparently terrorist action etc. So the real point is: do we damn want to allow proprietary hw and private made/designed such complex tools instead of imposing publicly developed FLOSS code on open hw made out of public research? Artists have envisaged tragic scenarios from Terminator to Matrix passing through Gattaca and Minority Report, techies have read much more substantial and realistic nightmares, civil society answer? Not seen so far...
