Yesterday evening I was picking up an Uber passenger at SFO. I saw an Uber car at the same location I was doing the pick up with the backdoor wide open and the driver outside the car on his phone. According to my Uber rider who was witnessed the incident before I arrived, a random guy hopped into an Uber car he did not hail and was refusing to leave!! The two riders who actually hailed the car were there too (the same scenario as in Miami, though, the guy who commandeered the Uber car looked totally calm!!). The driver called police and they were yet to arrive! I hope the issue got resolved peacefully.
