Should you happen to be one of the first drivers to buy a Model S or Model X with Enhanced Autopilot support, you're probably wondering when you'll actually start getting those features. Well, the mystery's over. Elon Musk informs a new Model S owner that the Enhanced Autopilot update should start rolling out in "about three weeks" (as of November 26th), or sometime in mid-December. That's a nice holiday gift, we'd say. However, don't expect to receive everything that Tesla promised right off the bat.
