The vehicle, one of a number of adapted Caravans in service in Philadelphia, is Uber’s answer to the ongoing problem of providing car service to people with mobility problems. The company is making adapted Caravans available for lease by drivers. Uber’s peer-to-peer business model, which largely depends on drivers using their own vehicles to provide rides, means the vast majority of vehicles available through its service are not wheelchair-accessible. The leasing offer incentivizes drivers to get these Caravans on the road. “Initial phase, we hope to see dozens of these WAV [Wheelchair Accessible Vehicles] hitting the street,” said Jennifer Krusius, Uber’s general manager for Pennsylvania.
