Why is Uber allowed on public roads?
Ultimately they will blame humans, humans are the bugs in their code.
I don't even know what to make of that
What exactly do you mean by "deal with driving"? Drive without a single accident, ever? That's obviously impossible in practice. Drive better than humans, who in 2016 killed 37,461 people in the US alone? I don't see how that would be impossible - human drivers have a limited field of view, slow response times (average time to break is ~2.3 seconds), and are frequently distracted, sleepy, drunk, etc.
This is one of those self correcting problems, and it's going to be fixed way faster than the startups pushing this "smart machines" propaganda are going to like.
