I've been using it and I really like it. The cars are always clean and comfortable, you can choose the music, and you don't need to talk to anyone. A couple bucks more than Lyft/Uber though, and there was one time it got stuck negotiating a two way one lane road when another car was coming, but people have trouble with that situation too.

The first time you take a ride in one is really amazing, it really makes you think "I'm living in the future." I recommend anyone visiting SF take one.
