I used BART and Caltrain for few weeks in total between 2006 and 2012. The experience was so much worse than anything in Europe. Caltrain and to lesser extent Bart felt like everything was falling a part and people just gave up. And then the was the smell. Even Moscow underground was significantly better. There you got occasionally extremely smelly homeless people, but it was like each 20th trip, not each second or third. And in Norway I meet a situation when one does not want to seat near someone on a bus or train perhaps once a year.
