I understand that there are quite a number of threads discussing Tesla's AP both in investor section and else where. But I specifically wanted to discuss Tesla's Autopilot functionality vs competition. I believe it's relevant to investors so creating a thread here. Many people have said lane keeping and active cruise control are available in many other cars. Mercedes S-Class has collision avoidance which they highlight on their website. So what is special about Tesla's autopilot? How is it better/different? I read Model S can change lanes on tap of turn-signal. Does it work? Is this unique to Tesla? What else?
