My car makes it slightly difficult to change lanes if I don't signal, some resistance on the steering wheel and a warning beep beep beep that I'm "drifting." There are some terrible roads around here that confuse the sensors so I do a bit of steering wheel arm wrestling now and then just to keep going straight.
It was when I was holding leftmost lane position passing a semi and it beeped and tried to steer me into said semi that I decided it can fuck off for ever lol
How strong is the lane assist in your car? If I was weak enough to even be bothered by the lane assist in my car, I'd figure it was time to stop driving. It certainly has never come close to overriding my steering.
