Space in the market for luxury public transit?
jrockway: It's been done.  Trains in Japan have the option of paying more for the "green car" or a "liner" instead of the regular railcars or regular trains.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.)
