Marco Arment:

A few Tesla vehicles have had accidents with Autopilot enabled recently, and I’ve gotten countless questions about these incidents and the nature of Autopilot from people who aren’t Tesla owners. Tesla and the media haven’t clearly communicated what these features do (and don’t do) to the public, so I’ll try to help in whatever small way I can as a Model S owner for a few months so far.

This is a terrific walkthrough on Tesla’s autopilot, a glimpse into what’s coming for cars in general, as well as a reality check on where autonomous driving stands. Things are changing fast as we move towards autonomous vehicles all around us.
