They have a bunch of driverless cars driving around at night, but they've so far only been serving a handful of rides per day, and there's a waitlist to get access. So it's not really open to crazy drugged out criminal anti-tech folks OP was talking about yet. That said, I don't expect this to be a big problem given the cars are loaded with cameras. There will be people who create mischief but they'll quickly be banned from the service.
