I sold my Model S to buy a new one specifically because of the "auto pilot" feature, and Elon's promise that soon (June or July) software will enable the auto-steering function of the car. I will not be too upset if the car only keeps its lane and does not automatically change lanes and pass for you. But I didn't know it was impossible - as this guy says. So, I'm asking my very educated forum fellows - what do you think about this? Teslaâ€™s game-changing, lane-changing Autopilot? â€œCurrently, there is no radar on the market that can achieve that,â€ Toyota engineer says - Daily Kanban Just for fun let me ask a second question: Do you think Tesla would be smart to make plans to replace sensors on the cars it sells with "auto pilot" hardware as needed to keep up with the industry in the next 5 years? Or should Tesla just say "tough luck" to those of us who buy the car now, and get stuck with very limited auto-pilot ability compared to a car that comes out in a few years than can over-take on its own? Is customer goodwill worth anything to Tesla?
