OK, here is a better link suggesting that the 54 cent/mile rate mentioned by the WSJ article isn't just about undercutting Uber but also about avoiding legal problems. http://kxan.com/2014/02/25/ride-sharing-app-gets-green-light-from-city-of-austin/ http://kxan.com/2014/02/25/ride-sharing-app-gets-green-light... From the article: "Heyride, a ride-sharing program, was forced to shut down operations in the city because drivers did not have permits, the Austin Transportation Department said. The city says when drivers can set their own rates and earn a profit, that’s when they’re treated like taxi cabs. “It’s not friends taking friends, it’s the money being exchanged, the compensation,” said Steve Grassfield, with The Austin Transportation Department. With Carma Carpool, riders pay 20 cents per mile and drivers earn 17 cents per mile to pay for gas and car maintenance. Federal regulations say drivers who earn anything less than 56 cents per mile are not considered vehicles-for-hire."
