A group calling itself Arcade City Austin/Request A Ride organized itself on Facebook. Started by Christopher David and Eric Green, the group has over 32,000 members today.

According to TechCrunch, when members need a ride they post their current location and destination on Facebook. Within minutes, potential drivers respond with an estimated time of arrival, a proposed fee for the ride, and a phone number where they can be contacted. Once an agreement has been made, group members delete the request.
