I tried charging to 100% for the first time and got 505km (~314miles). I got me MY in late Oct, never tried the "Trip" option until recently.
I was expecting to see ~525km (~326miles). Not a huge difference but is this how it is supposed to be?
I now have MY for about a month and I never saw that "P" on the screen to even test the autoparking. Is that something I need to enable? I have the FSD, so I am assuming it is included.
