Self-Driving Cars Can Handle Neither Rain nor Sleet nor Snow
Driving in dry / warm conditions is simple mechanics.  Driving in snow and ice is an art.<p>In snow and ice, variables that are typically constant or static become dynamic.  Formally dynamic variables now become multi-variable equations.  For example: travelling down a hill normally requires dynamically factoring for the extra speed due to the incline.  Under blizzard conditions you have to factor ice/snow volume, as well as the incline.<p>I don't want to share the road with self-driving cars in winter for a long time.
