Uber likes to undercut conventional taxi pricing, but it can get expensive if you're by your lonesome -- just ask anyone who has had to pay surge pricing to get to the airport. You may not have to cough up the full amount the next time you're going solo, though. The company has just launched the beta for UberPool, a service that has you sharing a car with strangers. If you're a tester, Uber will try to match you up with another person who's taking a similar route; whether or not there's another rider, your fare gets cut in half. The mobile app will also tell you who's being picked up first and the name of your buddy, so you'll have a decent excuse to start a conversation.
