People in this thread seem to have overly high expectations about what is required to drive on US public roads. Not even considering that each state has its own licensing and registration requirements, all states except one (Georgia) accept foreign driver's licenses, which means it doesn't even matter what you regulate if countries X, Y, and Z can just not care about it and refuse to enforce it.

Regulating self driving is a good idea but it's a tall order to cast beta software as the menace when there are more idiots driving on the roads at this moment than there will ever be Tesla products.
