But there are plenty of places that don't have much snow and ice where they should be perfectly practical. Ice shouldn't be a problem, they could swap to studded tyres in the winter just like we do for cars here in Norway. Snow would be a much bigger problem though I agree!

I'd encourage you to stand in front of it. Commercializing public walkways like this is fine, I guess, but as a human walking around for non-commercial reasons, I feel like you have the right to do whatever you want (within reason) that doesn't impact other humans.
