It's free parking that made America great. These days, the more one has to pay for parking, the more likely one is to be in or near a 'rat stronghold.

I like to espouse the view that people driving their own vehicles is a form of mass transit, and a pretty darn efficient one, too.

DARPA has shown that self driven vehicles are not that far from the realm of possibility.
