Want your Uber ride to be even cheaper? Don’t mind sharing a ride with strangers and making awkward small talk? UberPOOL might just be your perfect service. As reported by The Guardian, it’s rolling out in London today and allows Uber users to opt into a carpooling option with a very attractive 25 percent discount on the standard Uber fare. Sharing is caring. It’s not guaranteed there’ll be another user opting into UberPOOL in the vicinity, but if you don’t get matched you still keep that tasty discount. So basically, you get rewarded for being a chill and environmentally conscious Uber user, even if you don’t even right share (it’s the thought that counts). As well as making Uber even cheaper for anyone willing to share, UberPOOL also environmental benefits — more seats on bums and more cars making full use of their capacity means less cars on the road and less pollution. The option has been rolled out in a few cities and even accounts for half of all rides taken in San Francisco (half!), so it’s not exactly a new concept but it’s certainly taking off. We’re still waiting for word of when it will hit our shores but you can guarantee it's likely to. Gizmodo's Luke Hopewell wrote an interesting account of his experience in an UberPOOL and pointed out the one major flaw in the plan: as well as being hella awkward to ride with a complete stranger, if you hop our first, that complete stranger knows where you're going or where you live. The app doesn't give you the name of your riding buddy, but that's no guarantee you won't be Ubering home with a weirdo. While we wait to see how it all plays out, let’s just scroll through #yourtaxis and giggle gleefully over terrible PR ideas. Via The Guardian.
