What's interesting is that I don't think any of the problems you describe with mass transit are inherit to or really even related to mass transit. I think they are just our cultural problems, spilling over into public spaces, such as mass transit. For example, in Japan there are many less homeless people on the buses and trains. No surprise there though, as there are very few homeless people in Japan. Even in Tokyo there only about 0.1 per 100k, compared with 795 per 100k in San Francisco. If someone is in a car, that does naturally insulate them from the homeless people, though it certainly does nothing to alleviate the root problem of there being a lot of homeless people. If our homeless epidemic is so bad that it is ruining our public parks, transit, and sidewalks, one would hope fixing it would become a political priority. Unfortunately, there doesn't seem to be much political will in the US these days to take on big, difficult issues. :/ Also, just curious, where did you see the strategy of cracking down on public transit behavior that was effective?
