To begin, I hate cars. I live in cities to get away from the car lifestyle. Still I find public transit to be lacking. Perhaps it's the homeless people defecating on the floor 4 feet from me, or maybe it's the lack of customer service, the inconvenient stops, and the entitled bus drivers, but I wish there was something "more".
Quite a few people I know whose average profile is 20-40 something techie, upper middle class salary, etc drive even though they live in San Francisco. They seem to have less of a tolerance for the fist fights and the public urinals than I do.
Virgin America has been quite a wake-up call for the aviation industry. I fly to Seattle twice a month, which means I spend a lot on airfare. I would save $6k/year if I flew on Alaska instead, but the lack of service and comfort just isn't worth the savings to me.
Maybe there's a market for an urban transportation system which costs 2x-3x the rate of Muni, and doesn't have any subsidized rates, as a way to draw people out of their cars?
But really, how often are people actually defecating on the public transit? Maybe one time you read an article where someone said they saw that? Either public transit is really good in the cities I've lived in, or the problem is you rather than it. Just sayin'.
I am in a pretty high tax bracket and I would never consider "luxury public transit". If I don't want to take the train, I ride my bike instead. (I don't have a driver's license.)
