The new Autopilot features have been lurking in Tesla's latest electric vehicles for a few months and now they're ready to go live. For HW2 vehicles we're talking things like the Lane Departure Warning system, Autosteer at much higher speeds (80mph versus the previous 55mph), Auto Lane Change and the Summon feature. Auto Lane Change, as you might expect, will swap lanes after you activate the turn signal while in Autopilot. Summon is pretty self-explanatory as well, activating a self-parking-and-retrieval system that you can control via the Tesla mobile app or your key fob. The newer HW2 vehicles (produced after October 18th, 2016) rolled off the assembly line with better sensors and cameras, but this new patch brings the functionality up to par with the older HW1 models.
