I had an Uber driver coerce me into rating him a few weeks ago, while I was in his car. He had a BS reason for wanting the rating now, it was just a ploy to get 5 stars. He was also insanely talkative. Uber might be a little more professional, but one is also playing the odds.
Right now, I check Lyft first, and take that if available. Unless I'm in a downtown area, then I will check an actual taxi app ( flywheel or yotaxi in SF ). If the lyft cars are sparse, I take uber. Just so I can keep mixing it up and trying different services.
( Flywheel has a terrible new design where they ask you for a "guarenteed tip" before the car is called. I tried to bail out of that - I don't like tipping in general, and I really don't like tipping before I can judge the service ), and I was charged $6 for cancelling. Whoa. No wonder people don't like Taxis.
