I live in NYC, and at this point I rarely use Uber. This is one more reason not to.

When I call an Uber, I have to wait N minutes for the car to come. If I want a cab, I step outside my apartment and flag one down. Granted, I live in downtown, so that wouldn't work as well in the other boroughs.

Uber also surges. Yellow cabs are always the same price. It's usually cheaper than Uber.
