mass transit just can't work for most of the country. We don't live in suburbs and work in city centers anymore for the most part. We have mixed living and working areas, and most people live and work in different suburbs. This improves one part of their quality of life at the expense of another. Unless you're going to mandate people change this by rebuilding everything, I think mass transit is a pipe dream in this country. The real solution to the problem is increased telecommuting. The more people that are able to telework, the lower the impact on the environment. I'm able to work from home 80% of the time, which means that even tho I only get 18mpg in my nearly 30 yr old car, I still use less gas in a year than the average prius driver .
