What's more, people are forgetting that normal traffic does not go through wilderness, and roads are not just slabs of concrete in a line. We draw markings on the road. We put signs next to them. It stands to reason that as self-driving cars will be slowly deployed (I don't see them rolling out simultaneously in sunny California and in snowy Switzerland), we'll be updating road infrastructure with signs and other objects designed for AI drivers - ones that could help them determine road conditions better.
Considering how poorly current roads are maintained I don't hold out hope for anything that requires more maintenance. Many roads I drive on are not properly marked for human drivers as it is.
I'm sorry but I think this is a grossly over-optimistic view. If vehicle automation requires any upgrades to road infrastructure I see it being a total non-starter.
