I drove to work, no real problems with performance snows (Dunlop M3). Only issues were trying to change lanes on unplowed roads. My car would bottom out in the deep snow so it was hard to get out of the ruts.
The other issue was all of the slow pokes on all seasons or who were just too scared to drive at least 1/2 the speed limit. They kept slowing on uphill sections... almost got both of us stuck!
I left work early as I was worried the snow would get too deep. When I got home my whole grill was blocked with snow.
