I've been thinking about this a lot recently and was wondering what ideas some of you smart posters have re: a relevant public transportation system. What are some tangible steps that can be taken? Where would you start if you could make the decisions? What are some of the hurdles and how can they be eliminated?

p.s. I looked for another thread to post in but it seems all the pieces of a transit system have their own thread but there isn't one for public transit in general.
