But what is he saying in private to people like Peter Thiel? We have no idea... And amusingly, Hillary was heavily criticized by Trump proponents for stating the obvious about public vs. private stances. Every bit of Hillary's private talks was dug up, but we know essentially nothing about Trump's real intentions. (Maybe Wikileaks could get on the case? Hah.)
There's a lot to dislike about him and I don't think it's fair to speculate on positions of his he's given no evidence to merit speculation on.
One might make subtler arguments about how this (and much) technology indirectly benefits all of civilization in myriad ways, even in the face of causal fallout like that mentioned above, but we have not one scrap of evidence that subtle arguments will either be employed or considered.
Until Trump proves otherwise, I'll continue to think he's not going to act like current Republican leadership, because he didn't act like that during the primary or general election and his platform doesn't line-up with someone who would be against self-driving vehicles.
