That is one of the reasons I became a transportation planner in the first place - for once in my life, my race, ethnicity, gender and income didn't matter - everyone paid the same $2 fare.
I like it too, MHJ. But I'm going to disappoint you now: that "classless" system isn't entirely classless, and we may need to decrease our use of it.
I raise the issue of class and transportation because I have ambitious goals. We need to not just decrease emissions, but decrease them enough to head off global warming. We need to not just improve efficiency, but improve it enough to head off peak oil. To accomplish these goals we need to shift a substantial portion of people from cars to transit.
I know there are many people who agree with me. Over and over again I hear them asking, "what will it take to get people out of their cars?" Here's what it will take: classy transit.
In the US and other industrial nations, generally speaking the divide used to be between the rich with their private vehicles, and everybody else walking and taking some form of transit. This heavy middle-class patronage allowed for some cross-subsidy to benefit the poor. Middle-class taxpayers also got government to subsidize some transportation infrastructure that was also available for poor people. When private car ownership came within reach of the middle class, they abandoned transit and took their money and their political power with them.
We can't accomplish our pollution, efficiency and safety goals without getting the middle class to shift from cars to transit. If you disagree, I'd love to see your plan. Otherwise, the next question is how to accomplish that.
