I wanted to address this separately, I didn't quote the message where you were suggesting someone was spreading misinformation when I quoted you, and I wasn't responding to that. However, I am going to now. I do believe certain posts in this thread have some exaggeration to them, including the one you refer to here, but that exaggeration could come from half truths or one-off experiences. For instance, I'm 6'1' and can turn the wheel when steering assist isn't even powered (as happened to me during startup a couple times last year due to a firmware bug), but when I'm driving with EAP and trying to keep my Model X straight where it wants to veer into an on/off ramp, the counter-force I am providing with a firm grip with both hands often leads to a slight swerve away from said on/off ramp if EAP disengages. That is a normal thing in my Model X, and I have been in loaners where it disengages with next to no resistance.
As I mentioned a few posts back, my steering is stiff in general, I have had it to the service center a number of times where diagnosis was attempted on that specific issue and no issue was found (no less than three times). Today, on my first real EAP drive with 2018.21.9, my Model X beeped twice (I've never heard it beep before and there was no card on the IC when it did) and started swerving back and forth within the lane (to be clear I'm not sure if the beeps or the swerving were first), and my firm grip on the wheel trying to keep it straight did not disengage AP in spite of my fighting it. I'm not saying I couldn't have triggered a disengage with more force, but the amount of resistance I was providing most definitely should have disengaged it, however, I am hopeful that was a one-off experience that won't turn into a regular thing. So, while the premise is questionable (and I didn't challenge your questioning it in spite of my experience this morning), I'd suggest you might consider it could be an exaggeration as opposed to a fabrication.
