Absolutely agree with this niggle. The lane tracking function is alarming and annoying and not suited to winding British roads with worn lane markings - perhaps useful on motorways. It feels like you're fighting the car and you're not in control (which you aren't). It would be OK if you could simply disable it but unfortunately you can activate it by accidentally pulling the cruise control lever towards you (which I've done a few times when what I wanted to do was increase the cruise speed by a 5mph increment) -- and then, having activated it, the only way of deactivating it is by going through the menus on the screen. Absolutely NOT what you want to be doing while driving, so I have to pull off the road. This really needs to be addressed. Either it should be possible to disable it properly so you can't turn it on accidentally, or it should be possible to turn it off easily from the controls.
