Innevitably whatever public transportation you use the route will end up in the ghetteo.
This is a mindset that many people in the U.S. will need to get over before the "quality" of public transport improves: that busses, trains, subways are for "the poor".
I've been on the subways in New York and busses and trains elsewhere in the States. They're gross. Especially, compared to most of Europe (Italy, Denmark, Germany, etc). In Asia, they're also a clean. The mindset in Asia and Europe is "this is what people (not just the poor) take to get from point A to point B". There aren't school busses, the kids just take the same city bus/train/subway that all the other people take to get to work.
I've spent 45 minutes in the States on my daily commute staring at (and riding on) the bumper of the car in front of me. I've also spent 45 minutes, in Europe, peacefully riding the subway to work. I'm able to surf the web, watch a video, relax. I definitely enjoy/recommend the later experience.
All aboard the gold train!
