You mention other cars overriding your input. The most common is the auto breaking when it sees you are going to hit something. But my understanding is that it kicks in when it is already too late to avoid the crash. So it isn’t something that is involved in decision making about driving, it is just a saftey feature only relevant in the case of a crash. Just like you don’t ram another car because you have a seatbelt, your driving choices aren’t affected by this features presence. The other common one will try to remind you to stay in your lane. But it isn’t trying to override you. It rumbles the wheel and turns it a bit in the direction you should go. If you resist at all it stops. It is only meant for if you have let go of the wheel or are asleep. So I don’t know of anything that overrides driver input completely outside of being too late to avoid a crash.
