If you rely on a wheelchair, you've largely been left on the sidelines of the ridesharing phenomenon. While plans have been in the works for some time, there hasn't really been a concrete accessibility strategy. Uber is improving that state of affairs, though, by launching new programs to accommodate disabled passengers. UberAssist, which is launching in Houston today, lets you hail an UberX driver who's trained in accessibility and can accommodate folding wheelchairs. A follow-up coming in a few weeks, UberAccess, lets you order a vehicle with a wheelchair-friendly ramp. There's no mention of expansion to other cities so far.
