Sure, you google me a snow clearing device that will clear plowed snow after a 2-foot snowfall away from a bike lane that abuts a bunch of parked cars on a narrow street and also doesn't create a traffic hazard. Because that's what we deal with in my town.
Yeah, you do see that bike lane is separated from the rest of the road by a concrete line so that plow can plow that area separately from the rest of the road, right?
Do you think maybe, just maybe, it's possible that there isn't a single solution for every city and town in the world and there are unique problems they can face which make things other cities can do untenable? Is that even a remote possibility? Or does it not apply to plowing snow?
First of all, cars have a much greater grip on the road in icy conditions. So they can handle things like black ice when riding a bicycle on it would be extremely dangerous.
But sure, every small city and town with harsh winters are beyond relevance.
