I commute home to the Peninsula from downtown every day on BART and now the trains are packed like sardine cans with people stumbling over all the bags that are in the aisles and blocking the doors. Unfortunately, BART mgmt seems oblivious or doesn't care. Sometimes even during rush hours there are only 4 cars every 15 minutes. BART service to the airport used to be great; frequent, uncrowded cars but now it is only a dismal, miserable pushing and shoving experience.
