adapting the infrastructure to these cars

This is an important piece I have not seen addressed in the US. In places where there is snow and ice on the road a good part of the year self driving cars will need help from sensors and guide objects in some form. Perhaps sensors injected into the road? Humans barely manage in my area because people have a cognitive awareness and memory of the terrain. Road lines are often absent. Sidewalks are obscured. Even simple things like parking at the grocery store is relative parking and people just make a best-guess as to where a spot is.

I am also curious if any testing has been done in snow blizzards and squalls. Squalls can occur without warning and visibility drops to nothing.
