On one hand I see why you are being downvoted, on the other, for people who haven't lived in San Francisco, crime on public transport is legitimately real. I personally have friends who have had bikes stolen from buses and phones stolen from their hands. A lot of the stations smell like urine. There are signs of drug abuse, and some of the stops don't feel very safe at all. I've watched women be sexually harassed on busses and have had friends groped at bus stops. The public transportation experience in San Francisco is not just about the price or the timing, but about the safety and cleanliness too. Seattle buses have been known to be de facto homeless shelters, particularly the late night bus. On one hand, I understand the "what right do we have to kick homeless people off busses" argument. How are people supposed to get their lives back together in a car country if they don't have a car? On the other hand, I've been on buses with urine smelling seats or urine streaming down the bus and if I am asked to make a sacrifice by tolerating that to support another person, I will just avoid public transportation instead because I have the means to do so.

The vast majority of people in west coast mega cities who can, use uber, bikes, or their own car. Public transportation in San Francisco is often seen as a last resort. In foreign countries everyone rides the public transportation, so there is public demand for quality. Our transportation situation results in the economic classes most able to effect political power uncaring about the infrastructural rot that is occurring since they can afford to avoid it and it's not a better, more predictable offering than just driving yourself.
