Due to a lot of (stupid) reasons, public transportation in the US has a lot of homeless/drugged-out people on it. And due to crowding, you are often pressed up against them. It can be quite uncomfortable to listen to someone who smells like 3 day old liquor and urine tell you about how they hate all of the "niggers that keep taking the bus" (an actual quote said to me), while you are pushed up against them. My experience of public transportation in other countries has generally been way better.
