It's more that it's time consuming than boring, which obviously gets worse with urban sprawl. Sure, I can do all my "down time" entertainment, but I can't schedule anything else while I'm commuting which is the real issue.
Though many US city demographics are different to anywhere else in the world due to white flight - the "wealth donut" around a poor inner city rather rather than people getting poorer as you move further out in the suburbs.
Honest question: are any of the large European cities seeing the "white flight" phenomenon with the influx of poor middle eastern and african immigrants?
IMO it's the reverse; all the fun for young wealthy people is in the city centre, while minorities are pushed out to the suburbs. Old tenement buildings get reworked into apartments, warehouses in old industrial districts get similar treatment, etc.
