And if I read your parent correctly he's mostly driving on said "mostly clear" roads as well, since he mentions salt. If the road is salted and bare you're not driving in snow. You're driving on a regular road. That's not snow driving, period. When we've had fresh snow and you have 2 or 3 inches of snow that moves around under your tires, driving is way different. That turn you're supposed to go 50 kph in but would love to take at 70 kph under normal conditions? You really want to slow down because you really don't want to drive on your lane, you want to kinda drive in the middle of the road because you aren't actually sure where the lane ends as it's all just white. The snow will make your car move where you didn't want it to go and while you of course can steer against that to correct if you go too fast and too close to the edge of the road on a left turn you're gonna end up in the ditch. And you don't want to go 70 or even 50 if you're essentially making the road one lane. Sudden braking and all ... Of course a few days after the snow storm you have a hard packed snow surface that has had crushed stone (yes, no salt, the side streets here are not salted) spread on it. You can't drive exactly like it's summer but for the most part you can. You also now know where the ditch is (aka a wall of snow). Still, every year there's two places not 500m from my home where a snow plow regularly finds itself in the ditch while trying to clear snow and has to be pulled out. Even though they put down stakes in fall.
