Bing might be 90% as good as google, but when people are trying to search for something they are just going to use google. I really started to realize how useful Uber was when i was traveling internationally I just pulled out my phone and a car came. I didn't have to worry about what the rate was going to be. It might have even been above what a taxi might charge, but at least I knew what the cost was going to be. It just kind of works.
