Rate not ye driver poorly lest ye also be rated poorly JUN 14 2012
Here's an interesting little tidbit from the Economist about Uber...drivers rate their passengers.
At the completion of a trip, a passenger is asked to rate the driver; the driver, in turn, rates the passenger. Drivers who have poor ratings do not last long, Mr Kalanick says, while poorly-behaved passengers may have trouble securing a ride, since a driver can decline a fare if the hailer has a bad reputation.
I'd expect more of this credit scoring in the future...you might have trouble getting a reservation, a hotel room, or seat on a plane if you're an asshole.
