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?
