>Are drivers taking off and refusing at the moment of pickup in SF?

Yes. Although usually what they do is call first and ask where you are going to.

I've absolutely had times where I've had them refuse either after I got in the car, or they don't unlock the doors until I tell them.

Does anyone still pick up? After a few calls and cancelled rides, you quickly learn not to answer anymore if you want the car to arrive.
