they actually do this in places like Minneapolis. mainly because it's just too cold to be outside for prolonged periods in the winter. my friend walks almost his entire commute without going outside.
Yeah, so that system is only 9.5 miles, and claims to be the largest such system of connected aerial sidewalks in the world. Meanwhile, NYC has 12,750 miles of sidewalks.
That's a several orders of magnitude difference between the capacity of the two systems.
