I’m not a big user of Uber but I need to say that the experiences there are mostly better than your grandad’s taxi (pay up for Uber X if you want a better experience). Mostly cabs were/are badly maintained and some seem downright dangerous with shocks dead, idiot lights on, smoking tailpipes and just general crappy interiors. I once got in a NYC cab where there blood all over the back of the drivers seat, got right back out. Cabbies are quarrelsome and grumpy. One guy picked me up at my house obviously drunk. I mentioned Uber to one guy who became very aggressive. Got out at the next light. Ah the good ole days.
Now for Uber. If you pay to upgrade to Uber X it’s a great experience. One time I got in the wrong Uber (not X). They said silver Nissan at station 4 at the airport in Atlanta. Got in the car and he was obviously going somewhere else than where I requested. When he realized I was the wrong passenger the driver became extremely agitated and aggressive. My bad for not checking his plate, his bad for not checking the passenger out. He was the driver so it’s really his responsibility since I may not know these things. Also I could not leave a bad review as I did not know who this driver was. Always always check you are in the right car.
