As my original post stated I can't say if AP2 without no confirmation is better or not than AP1. I do know that I read complaints on here about AP2 that I've never encountered.So did you have an AP1 car before that you are comparing AP2 to? We drive AP1 and AP2.5 daily. I have to admit that our AP2.5 hasn’t had the Nav on AP W/O Confirmation update yet (it does have Nav on AP), our last update was over 2 weeks ago and it wasn’t available then. When going from one car to another AP2 is a bit of a letdown. One way is when traveling down the highway and the speed limit drops in a constuction zone, AP1 can see the speed limit signs (Mobileye has the patent) and will adjust your speed automatically, AP2 is totally oblivious to speed limit signs and will make no speed adjustment. AP2 still gets confused when the right lane gets wider and an exit lane starts, in that situation AP1 will maintain the same distance from the left side lane marker and handles those situations easily. AP2 is fine as long as Tesla eventually can work on its problems but my point is it is not really any step up from AP1 and a buyer of a used car on a budget is getting a bargain if getting AP1 at any discount.
Both TACC and AP adjust for speed. Works the same as my Garmin GPS did, reads them from a GPS connected database. Not 100% but pretty darn good. Infact autosteer or auto pilot when not using NoA restricts you to 5mph over posted speed. Frustrating sometimes.
I agree AP1 is an excellent system. My issue is it is what it is and is going to stay where it is. AP2 has improved performance and functions several times since I bought the car last November.
