> Most trips you take in a car are from one location to a second location and then back. Home to work, work to home. Home to store, store to home. You'll have to go backwards in your flying car too.

What PT advocates do not seem to get is that everyone works and lives in different places.

> Adding another dimension to travel doesn't make it better, and when progress fails to make something better, then that is not good progress.

There are plenty of environmentalists who think technology which enables more people to live is bad progress, so I don't think I will leave it up to you to decide what good or bad progress is.
