AutoPilot is the primary reason I'm interested in Tesla (and the Model 3). The 200+mile range, cool design, electric low maintenance drive-train, over-the-air software updates, clean interior, and an interface that doesn't suck are also up there on the list of reasons I'm interested in Tesla.
The auto pilot features are what first got me interested in the Tesla. I also like that they are fast and fun to drive yet still efficient. Also no internal combustion engine maint/problems.
