I can't find how it will operate. Will it detect a situation where lines are not painted sufficiently clearly, warn you, and disengage? Or will you need to detect where it begins to operate wonky because lines aren't painted sufficiently clearly and to take over? I guess it's the second. It's hands-off, not eyes-off. Also, I would like to see a car company that is further down the road of full autonomy clearly describing all the long tail scenarios. It's just impossible.
