If you've got EAP, you should have NoA, LK, TACC, and the car will stop at stoplights. You might not have the autopark, but that
will be coming.
So, we're back to your original question: NoA should be enableable on your car. If not, then there's a Problem.
If you want to chat about what you've done or not done, here on the forum, please have at it. But this is actually a time when going to the app and putting in a service request for help may very well be in order.
If you go the service request route, you're more than encouraged to put things like pictures in the request, so that picture you took of the screen where the NoA thing had the "accept" greyed out looks like a good idea for that. My experience with the app/service-request route has been good; one usually gets responses within a day and one can chat with the advisor; sometimes they'll actually call you. The Tesla types can look at your car remotely, especially if it's a software issue, and can reinstall software if necessary.
Just a couple of questions for you: The app on your phone is up to date? There's no other, "Agree to this before continuing" dialogs you skipped over? When running on EAP these days, you
do have to enable the on-board camera, thanks to our friends at the NHTSA, so if you turned off all data sharing, that might be a reason for what you're seeing. Please note that I'm guessing.
On the data sharing front: Tesla, unlike what I've heard about news reports from other auto manufacturers, absolutely does not sell your data, or "anonymized" data. The one semi-scandal I heard about this was that, apparently, the data that
was being collected (for the purposes of improving FSD and the like) was being accessed by
Tesla employees who were not involved in FSD/EAP/whatever. Once found out, said servers were locked down. Don't know if anybody was fired, though.
One last thing. Back when the SO and I got her a Model Y, she stated that she definitely wanted to cheap out, so No EAP nor FSD, etc. We got the car in 2021 and it came with a trial version of FSD. With FSD, one can set the software for either Standard Autopilot, EAP-style Autopilot, or FSD. (There's actually three buttons in a line..) When the trial ended, and the 2018 M3 still running FSD, she was back to Standard Autopilot. We took the her car on a trip or two.
Changing lanes with Standard Autopilot is straightforward, and not particularly awkward: One just puts on the turn signal, turn the steering wheel over the slight bump so it disengages, and go into the new lane, keeping one's own eyes open for other cars, although the blind spot indicator will show if somebody is out there. Then one has to re-engage SA by hitting on the lever again, and one is off down the road again.
But, with EAP, one can just hit the turn signal and the car will shift lanes on its own, keeping an eye out (with all the cameras) for not only people in the blind spot, but speeders or whatever coming up on the blind spot. So, no question, EAP is
safer on interstates. After some discussion, we decided that EAP, which I think is half the cost of FSD, was the way to go; she could do without the (at the time) craziness associated with the Beta FSD package. And that's where her car is, at present. EAP is definitely worthwhile and has everything that FSD has, except for the city streets.
