Yesterday I went on my very first test drive at the Burbank store. I don't know if the salesperson said anything outright wrong, but she did give a poor demo of AP for me. I am sort of familiar with AP from the discussions here, but hadn't ever seen it in action or paid attention to the nitty gritty of how to set the various functions.
We got up onto the 5 in slow bumper to bumper traffic. I asked to see an AP demo, and she instructed me to pull back on the stalk twice (that was the extent of any AP explanation, BTW). The car immediately surged forward towards the car in front of me (I had left a large gap) which surprised me and made me immediately hit my brakes to disengage the system. Since I had been following here, I figured out that TACC was set to 65 even though traffic was moving like 20. I asked her how to reset the max cruise speed so it wouldn't surge when I engaged AP, and she didn't seem to understand my issue and just told me to pull back the stalk twice again. I did, and the car surged forward, again. I reacted by braking, again. She then started talking about setting the following distance for the car in front, and I think she set it longer (I wasn't watching). I closed the gap to a car manually and engaged AP again. This time I was within range, and the car didn't surge. But I then managed to disengage Autosteer since I was still so nervous about the prior two events. She did quickly spot that (kudos), and we started again. I finally managed to get full AP engaged and let it drive for a little bit, but I was thoroughly unnerved by the system at that point vs completely sold.
I had been previously on the fence about waiting for an AP CPO to come out or maybe buying a 60 new, but now I am back to wanting a regular old S85 CPO and saving my money. So, she inadvertently saved me money, which probably isn't Tesla's long term intent
