In that case we had self-driving five years ago, I guess OP meant mind-off self-driving. That's the hard part, it could even be an AI-hard problem. Because if you have to pay attention with hands on a wheel, it's not a huge convenience improvement. And there's also the problem that human-take-over situations will be increasingly dangerous as the self-driving software improves.

And by the way, the auto-pilot video is underwhelming. Several companies have more advanced self-driving tech than Tesla, e.g. Waymo is at least 3 years ahead.
