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 Manhattan Supreme Court Tuesday by Disability Rights Advocates.
