It's slower, a round trip I could make in 30 minutes in a car would take careful scheduling and two hours on a bus. Sometimes it's cold outside and I'd have to walk half a mile to and from a bus stop. The local transit authority is experimenting with reducing the number of light rail cars so they'll be better covered by transit police in cars because violence is a problem. Once on BART I'm convinced somebody shit in a paper bag and left it in the middle of the car. Caltrain in rush hour would be a violation of the Geneva Convention if you made prisoners stand in such a cramped and unstable train for an hour at a time. I keep hearing about people getting stabbed by the local bus stop, 45 minutes after a friend visiting me came through the last time. A couple of months ago a dude died in the hospital after getting stabbed on a bus three blocks away from my apartment in a dispute over who got a cigarette left on the floor of the bus.
I calculated total cost of ownership of my car and it was considerably less than taking public transit unless I used public transit a lot, and any savings would be completely blown away by using Uber for just a couple of trips a month.
There are situations where public transit is a good thing, but it's generally a dirty, crime-infested, unpleasant experience in America only good for people who are really excited about not having a car. I'm opposed to any measures that force public transit on people by making car ownership more difficult until after they make public transit a safe, convenient, comfortable experience.
