To be clear, I'm not talking about auto lane centering. That's something else. The Nissan has this too, but it has to be manually enabled and although it seems to work alright, I just feel like as a driver, it's my responsibility to control the wheel.
What I'm talking about is lane keep assist, which is a "safety" feature which beeps at you and jerks the wheel when the car thinks you're veering out of your lane.
