I am specifically talking about things that take over control of the vehicle.
I've had lane assist fight me when trying to move lanes. I apparently wasn't turning the wheel enough and it thought I was drifting (I wasn't).
I've had another hire car refuse to move backwards without me putting it into reverse. It had anti-rollback measures. I didn't know what was going on. All my other cars would rollback (I drive manuals). Now I know technically you shouldn't coast backwards but it was maybe a foot.
Sure it does. You can tune it to get better performance or fuel economy. (Tbf, you can do the same by fuel mapping your injectors, but it would probably void any warranty).
What you seem to be alluding to is that the automated features give you different performance than what you were expecting and you have little recourse. The same could be said for your fuel injectors.
Not being snarky, just pointing out we’re often guilty of picking and choosing rather than applying first principles.
