A friend just got back from Scottsdale, AZ and said they called for an Uber to take them some place and the car showed up without a driver. They got in and it took them to where they wanted to go and there was no voice recording or anything confirming their destination they just trusted it and it worked just fine. I knew this was coming but I'm thinking I might want to wait a while longer to see that the driverless vehicles have a proven safety record. With Uber you may not have a choice because my friend didn't know she wasn't getting a human to drive her.
