But other countries have far fewer accidents than the US so it isn't quite so black and white. The gain from autonomous vehicles will be much less in the UK for instance. If you really want to reduce accident rates you need to improve road design and encourage more use of public transport and cycling. This requires no new vehicles, no new software, no driver training, and doesn't need autonomous vehicles at all.
