You couldn't build most buildings in Tirol in the US due to zoning restrictions. When we lived in Innsbruck, we had an apartment with no parking spot. Here in Bend, there is tons of parking, because people regard automobile storage as more important than places for people to live.
And still rents and apartment prices are exploding in Innsbruck. Even couples that broke up keep living together for months because the affordable housing situation is dire
Not sure how you are going to convince people who live in a blizzardy mountain town to start walking to work en masse. Snowmobiles are popular in the winter at least.
My wife, baby daughter and I lived in Innsbruck and walked or biked to most things. They clear the streets and sidewalks pretty well. It gets a lot of snow - they hosted the winter olympics there twice.
Innsbruck is not a mountain town, it's the biggest city in the Tirol with >100k residents. I have yet to see someone riding a snowmobile through the city
