You're talking about one variable I'm familiar with, but it's one variable. With snow cover in a plain, you just drive much slower and turn on your hazards.
Headlights of cars in various states, and some drivers think they have them fully on when they don't.
I'm generally enthusiastic for electric vehicles, but batteries and FSD don't really work in a 12 hour blizzard at -40. Doesn't match my use case. :)
Try starting at the east side of pooass Manitoba if you want to contend with sketchy road conditions. By the time you get back to Regina your cortisol levels will be telling you to back out of the trip altogether
