A nonprofit disability rights organization filed a class-action lawsuit against Uber, claiming the ride-hailing service discriminates against New York City riders with disabilities by not providing enough access to vehicles that can accommodate wheelchairs.

"Having grown rapidly since it began operating in New York in 2011, Uber provides hundreds of thousands of rides a day in New York City, but for riders who need wheelchair-accessible vehicles, it provides vastly inferior service, or in many cases, no service at all," according to the lawsuit filed in New York State Supreme Court in Manhattan on Tuesday by Disability Rights Advocates.

The lawsuit said that although Uber offers wheelchair-accessible vehicles through its UberWAV service, they account for fewer than 100 of the 58,000 Uber vehicles dispatched in the city. It said the special vehicles can be used by other riders and may be unavailable for use by disabled riders, who "face extended wait times, or are still denied access to the service altogether."
