What problem is this solving? NYC doesn't have a problem with people either not being able to drive or not knowing where they're going. We have workable (for an American definition of workable) mass transit and several livery services including taxis and Uber.

We're trying to get rid of cars here. Congestion pricing, the widening of pedestrian and biking thoroughfares, just to name two initiatives. We don't need more cars, regardless whether or not they're being human-driven or not.
