On thing not included in the above conversations is enhanced auto pilot. EAP includes many features which are included in FSD, but are NOT included in basic auto pilot. I bought EAP in 2018 for my 3, as an option, and, to my knowledge, it is no longer available for purchase. EAP includes summon (smart?), auto park, auto lane change and navigate. However, I do not have traffic signal and stop sign recognition or navigate on city streets. Dilemma: I have an S on order and I wish I could take EAP with me, rather than purchase FSD.
