> What of the lone-wolf terrorist, placing explosives in a programmable car? At a National Highway Transportation Safety Administration hearing in April, one speaker urged the government to require sensors inside autonomous cars to sniff out hazardous materials and disable the cars if necessary. How does that make sense? They are talking about "hackers" seizing millions of cars remotely in one paragraph, on the next we have perfect technology that can sniff dangerous chemicals and disable a car. But wait, aren't those people supposed to be hackers? Why can't they disable the sensors then? Also, what's preventing them from retrofitting a car to be remote controlled, if they are so skilled? Newer cars are almost "fly-by-wire" anyway already.
