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.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.I don't want to share the road with self-driving cars in winter for a long time.
