Just took delivery of my Model X 90D from Tampa SC Thursday. Absolutely loving the car! Have a quick question and Looking for some feedback. Took our first decent trip yesterday already. 3 1/2 drive to Daytona Beach, FL from Sarasota, FL. My 2 main concerns. 1- On lightly paved highways even with decent markings the autopilot has a very hard time recognizing the lines. I was unable to use autopilot as it was focusing on the car in front of me VS the line markings. I could feel the car move with the car in front as it would move from side to side in the lane. I'm thinking this is just because the lane markings did not have enough contrast? 2- I am still a little freaked out with autopilot on the interstate at higher speeds. Everything seems perfect with a good flow. However, if I am going 80mhp and I come up on a traffic jam of much slower we or stopped cars I still feel like it isn't going to stop in time, or it's just going to slam on the brakes at the very end once close? Am I missing a gradual decrease of speed setting coming up on stopped traffic? I even had it set to 7 car lengths. Any help would be much appreciated. Pulled into the hotel and was treated like a king by the way. Lol. Had a crowd of about 30 people as soon as the FW doors opened. Also got a VIP front parking spot under the cover right by the hotel doors in valet. Thank you all!
