Hahaha... yeah, I was skeptical too. But in all fairness, there were a couple other people in the car (although I didn't feel crammed in there), so they were making more than $29 for the trip.

I actually talked to the 'pilot' for a while and he explained how the biz works... they're making money. The route is driven multiple times a day with several passengers for each leg. One of their vehicles has over 300k miles on it in one year!
