Highway Autopilot is free and included on all current Teslas. For an additional 10k you can do a software upgrade to FSD which does things like lane changes, and autopark, and summon. Someday, it will also hopefully do this for city streets (15 public users are on a beta of it right now). But yah, you would never buy this on a Tesla, as the car includes a better version of it for free on all cars.
