This entirely tracks to me but hints at a different problem. I suspect if this really does reduce traffic incidents and fatalities in general, it's because a large number of people are driving while tired and drift into adjacent lanes without realizing it and the lane-assist jerks them awake. Problem being this is a blunt force instrument that annoys or even endangers drivers who are not impaired and know what they're doing.

Thankfully, every car I've ever driven that has this feature allows it to be turned off and I have it turned off on my own car, which I drive for maybe ten miles a month in the middle of a Saturday when I'm wide awake.
