Unless they cancel the ride, and you ignore the notification.

I was talking to someone recently, and they were telling me about how they got a (Lyft, I think) ride from the airport (JFK), and the driver picked them up, and said that the ride had been canceled (as they got into the car), but that for $20, he'd take them where they were going (I assume the ride was less than $20).

Apparently, this is fairly common. There's been a couple of articles about how the Uber and Lyft drivers around JFK and LaGuardia have learned to game the system. They can also conspire to drive up the pricing.
