There's typically a button to toggle it on/off somewhere near the steering wheel.

I got a new car a couple of months ago that has this, and was experiencing similar issues on rural Texas farm roads. I just had to look up where mine was and turn it off temporarily.

I have an Audi - the button to turn it off and on is at the tip of the turn signal stalk. You can toggle it with your pinky without removing your hands from the steering wheel or eyes from the road.

I also have a Subaru - turning it off or on requires three levels of menu navigation, and you have to use the center console touch screen.

I suppose they do their testing and validation in drastically different environments!

I have a VW with similar technology. Even on regular highways it's attempted to veer off onto an exit pretty consistently.

My Kia lets you set the level of correction as well. So it's can be gentle, "uh, pay attention", or "get over here!"
