I did a follow-up test. Not only did adjusting the volume via the steering wheel scroll wheel after 9.5 minutes
not prevent the nag, I actually got a forced disengagement got the first time at the 10 minute mark (or so).
Idk why I got a forced disengagement this time and not on my previous test drive, where I went the full 10 minutes without touching the steering wheel twice and only got a “nag” each time. Maybe the software gives you a pass on the first drive where it suspects a cheat device, or it only gives nags on the first two 10-minute intervals and then gives you a strike on the third.
And, just like someone else reported earlier, I got an “FSB Beta Warning” or strike recorded against me, even though I have FSD Beta disabled in the settings and was just using regular Autopilot. So now I’ve only got 4 FSD Beta strikes left.
Maybe tomorrow I’ll try repeating the test but after 9.5 minutes I’ll give the steering wheel a tug instead of just flicking a scroll wheel.
