There is one city in the world where Uber can not fail, cause if it does, it will be the end of Uber, and that is Los Angeles. Los Angeles has always been the perfect city for Uber, with its incredible vastness. Its nearly impossible to hail a cab in Los Angeles, and unless you are at the airport or a major hotel, there isn't going to be one around. If you call for one to come to your residence, in most cases, its gonna be 20-30 minutes before they show up, if they show up. And I haven't even gotten into the price difference, and the smelly cabs. Uber can not fail here, cause if it does, it can't be successful anywhere. There really aren't enough drivers to cover Los Angeles to begin with, so if Los Angeles drivers said enough, and started a strike, and were committed to it, I guarantee uber would be forced to change their rate structure for Los Angeles county.
