> flat-rate fee per-person for transport

That was not the case. I remember paying a different amount than the person I was sitting next to, because we were travelling different distances.

True. It's a flat rate for a given town or neighborhood. You won't be charged for traffic delays as you would in a cab however nor can the driver charge you more if he needs to detour around road construction or some other issue.

The rate is the same for everyone in a given "zone" regardless of the specific route the driver must take.
