What kind of idiot mistakes assistive technology for autonomous driving?
The Tesla Model S is no self-driving horseless carriage. It has an autopilot, yes, but it is a long way from picking you up when you call it on your Dick Tracey watch.
It doesn't drive for you. At best, it makes driving easier, like an automatic transmission or a cruise control, and maybe safer, like an anti-locking braking system.
It is not a self-driving car. If you are looking for one of those, you are at the wrong company, and should look at the Google car instead.
