I am also on the fence as OP. I do tons of interstate long-distance drivings at the moment so EAP would help tremendously. One question to you all that have EAP or FSD. With NOA off or auto-lane change off, when you signal for a lane change, will the lightly tap on the stalk (which gives you 3 turn signal blinks) work? Or you have to engage the turn signal stalk fully downward or upward?
So I was the person that said you really need to push the stalk all the way to initiate the lane change if you're not auto-changing. Now that isn't exactly true... my first time using Autopilot I put into this forum my experience and it was funny- someone replied something like "You should read the manual before you use a feature that has your life in its hands..." -Fair Enough... so I did..
There are fairly detailed instructions about how to use the feature and the stalk in the manual... and I bring this up because it includes things like pushing the stalk will cause the car to accelerate to pass, etc. Here is just one of the notes:
WARNING: If you have purchased an optional Autopilot package and Traffic-Aware Cruise Control is active, engaging a turn signal can cause Model Y to accelerate when using Traffic-Aware Cruise Control in specific situations (see Overtake Acceleration on page 86). If Autosteer is active on a vehicle with Auto Lane Change, engaging a turn signal may cause Model Y to change lanes.
Definitely check out page 86 in the manual located here.
So what I'm saying is I recommend looking at the manual... BUT in my experience, if I don't push the blinker all the way- sometimes I change lanes and most of the time when I let go the signal (I guess too early), the car dives back into the lane I was in... and that upsets my passengers... BUT its really easy to just get used to pushing the signal all the way- I mean the car is going to do all the work after that so its no big deal to push the signal all the way vs holding it for 3 seconds.
Hope this helps.
