People need to get real and start calling it what it is. It's a taxi service. This is not ride sharing. The driver was not already going somewhere. The driver was waiting around for a call to pick someone up, and was going to take them where they wanted to go. Nothing is being shared. This is a Taxi service and the Uber app is the dispatcher.

If I was already going to work, and I picked someone up along the way, that's sharing a ride.

The only thing the driver is sharing is the money they are giving to their mechanic when all the around town driving wears out their car.
