There are very few people who love driving in snow and slush, and those who do are mostly Norwegian rally car drivers. Most of us dread it — the fender benders, the ditches, the whiteouts. It would be great if an autonomous car could just do that already, but it can't. Not yet, anyway. The current crop of self-driving cars rely on cameras and sensors to see the world around it, which includes lane dividers and the white line marking the edge of the road. When snow and slush cover those up, autonomous cars wander around in the street like drunken robots.
