I think your sales rep was repeating a confused idea of calibration of the ultrasonic sensors for autopark. That is supposed to take a little while. My experience with a new AP(1) car: I took delivery of the car with 11 miles on it. I drove about five miles on surface streets to a limited-access freeway, merged into traffic and engaged AP. It was fine, even when the traffic turned to stop and go in light rain. I monitored AP closely, but I only had to take over when there was merging traffic. That's always a concern with AP(1), because of its limited sensors. I would not have trusted AP with traffic lights then, and I still wouldn't. AP(1) doesn't support traffic lights, and they create excellent opportunities for mode errors in human drivers.
