Damn, that's super annoying. My Ford truck has a similar feature, but at least it's possible to turn it off permanently. I usually leave it on the "vibrate steering" / warning only mode, so if you're distracted it'll warn you but not actually take over.

When I first got it and was towing a trailer through some narrow curvy roads it was downright dangerous because I needed to cross the center line to stay on the road, and the truck was trying to steer me off the edge.
