that's the blindspot isn't it ? What's the one common thing about recent terrorist acts ? Vehicles used as weapons. Yet nobody's calling for a ban on the use of vehicles
Even one level up... Since when is a crazy individual with a knife in a car a terrorist? He's just a crazy idiot and we should call him so. If this is modern day terrorism we have nothing to be worried about.
Only because it is not yet feasible. Once autonomous vehicles become common there will be pressure to make driving a car manually difficult, expensive, and ultimately a crime.
