I have owned my 2021 Model Y for about four months. I live in a relatively rural location on the Olympic Peninsula in Washington State. I have received conflicting information about AutoDrive from multiple sources so I want to clarify a few points with users who use it and understand it well. First of all, once an address has been added and the Blue Navigate on AutoDrive comes up, is it on at that time (after you engage the Autosteer with two down clicks on the right lever) or not. I have been told by others that you must press the Blue button for it to be on. AutoDrive seemed to be active for me today while driving on a four lane expressway while the Blue Navigate on AutoDrive was lit. What I saw today was a Blue line coming out of the front of the car on the screen. Does that centered Blue line mean that AutoDrive is working and engaged? Or, is that Blue line only there when changing lane or exiting the highway? If you are engaged with AutoDrive and AutoSteer but are on a two-lane road, you see the two blue lines on either side of your lane. When you just have the two blue lines, does it mean that Model Y is not in a location where AutoDrive can work and that you will only get AutoSteer reaction from the vehicle. Hopefully, the above is clear enough for a frequent AutoDrive user to understand. Help with answers to the above will be greatly appreciated.
