The seasonal change here in the mid Atlantic region is not severe, but I can see where your tip would be good for Canadian and Minnesotan neighbors.
At this time of year, the main safety hazard here is wet leaves on the road. In southern CA, where I used to live, the main hazard is a little rain after a long dry spell. Cars spray miniscule bits of oil on the roads, then the first rain lifts the oil slick, making the roads very dangerous.
