One would assume long term the snow plows would be automated as well, and therefore be clearing in a way automated cars would make best use of.

I'm curious how they'll handle whiteout conditions, however.

You'd hope, but many area's "snow plowing" means the locals get together and hire someone with a road grating tractor to come and plow. AND if they have the extra budget toss some dirt on there.

:-) Obviously this doesn't apply to country or greater highways.

On the other extreme, Montreal's snow clearing costs an average of $155 million per year.

With I would assume a large portion of that going to labor costs. Automated snow plows could be a huge help.

Lane following tech is an area of active research for snow plows. I guess it frequently relies on installed roadside infrastructure though.

Edited to soften the first sentence, a quick search didn't find any active users, just research.
