Uber, the San Francisco-based car service that will find you thanks to an app on your smartphone, got a lot of ink and took a lot of heat around New Year’s Eve for its “surge pricing.” That is, the price of an Uber ride would go up if demand was high. Now, Uber is turning a tables a bit, announcing what it calls “Surge Drop,” a way to take advantage of a drop in the price of a ride. Essentially, it says that because of demand fluctuation, your ride might cost less than expected, and Uber can let you know via your iPhone if you can snag a cheap ride near where you are.
