I have a friend who bought a Model X without autopilot, I was stunned because it is probably the single most important feature of my Model S. In fact I think that features of Teslas like traffic aware cruise control, autosteer, radar controlled emergency braking, could be ported to pretty much any modern drive by wire automatic and would be very beneficial. But Mercedes who have had much of the necessary hardware for decades make it a premium option on cars that are already very expensive so it hasn't happened and VW has emergency braking on some models but I think it is still optional.
