Your argument is essentially that just because you don't need/like Uber doesn't mean it's useful? The problem Uber is addressing is not just a US problem - with Uber you essentially don't have to deal with all the shit taxi drivers pull, like refusing rides if they have to go to a slightly less profitable area, overcharging for rides for people new to the area/tourists, etc. Not to mention that with Uber you know exactly when the driver is coming, how much you will be charged up front, etc. You may not like how Uber is addressing these problems - and indeed there are fair criticisms, but ride sharing apps are most certainly solving a real problem.
