I had a similar situation. Uber driver calling and saying he was there and what area he was in at the airport. I am in the same one and not seeing car or license plate. We talked on the phone until we found each other. He had taken his other car today (apparently he had 2 that he would use to drive uber). Face matched, name matched, and my pin code unlocked the ride. Oh and this was in FL, and he had a CA phone number and a Dodgers hat in the window too so seemed like that matched a bit too. I did pause before getting in, but it was fine and he got me to my resort no problem.
