I got TJA... but I don't use it because I don't like lane assist. It was one of those layered options you could get on the first
Ateca Xcellences. Given I don't use it, I have not experimented with its lane keeping abilities at slow speed. Just believe in driving the car rather than being frightened by whether the car can drive itself with it's limited abilities to do it. It's not a Tesla and they sometimes kill the driver. Need good white painted lines to stay on course.
