Lane assist is a product of the pervasive "what works in urban San Francisco/other coastal cities is the right solution for everyone" mentality. Unexpected obstacles are far from the worst of its problems on rural roads. Lane assist doesn't give a fig about the fully loaded dump truck coming around the inside of the curve at a relative speed of 100mph within inches of your door, because that situation just doesn't exist in urban environments. (You are supposed to be all over your white line in this case, in case it's not obvious). Conversely, headlight tech which matters much more in rural environments (oncoming headlights are too dazzling on dark roads, and your own headlights are too dim - current legal tech fails both ways simultaneously) is irrelevant in urban environments, so it is literally illegal to improve.
