I was going to reply to a couple of their posts, but your post seems to sum it up quite nicely. Please note that the following comments are certainly not directed at you.

Not every neighborhood or community is laid out to be convenient for non-motorists. That will not change overnight.

We don't always have the option of living close to work, especially those of us with specialized job skills. If there is no acceptable housing near the hospital, should a doctor choose a different line of work?

Not everyone that drives an SUV or even a car is worried about gas prices. There are plenty of people making enough money to shrug it off. The recent increases have cost me and my wife about an extra $6 each week in gas. Ho hum. But we've watched our weekly grocery bill steadily increase a lot more than that $6. Raise the cost of gas, and sure, I can use my car less. But what is the car-free person going to do - eat less?
