Probably not even necessary. How many days do cities with snow actually have snow sitting on the roads? A dozen or less?

It’s less so snow sitting on the roads as to the melting and freezing cycles over night that’s the issue. Plus I’m in Canada and sometimes a polar vortex can keep it so cold that even road salt doesn’t work and ice remains on city roads.

In that case snow + ice = bad time to be self driving and lack the intuition of a human driver.
