Promoting the system with the name 'Autopilot' is, to my mind, quite a bit less than extremely clear communication. This name provides Tesla's critics with a constant line of attack, which will continue right up until they reach level 5. I consider myself a hardcore Tesla fan but I think they've botched their messaging, and this latest statement isn't helping.

Well, that's exactly the problem, isn't it: people keep getting confused. If your message isn't getting through, instead of just yelling it louder you could try eliminating all ambiguity, for instance by changing the name. If this were marketed as simply 'adaptive cruise control with steering', nobody could claim they were misled.
