The alert turns off eyesight, or the weather? TBH, I have a 2021, so some changes I am sure in the last two years and it has yet to turn off on me in snow or rain, day or night. I get that it will, but... and honestly, I would prefer being the one controlling the car in snow than letting it do it... and I used lane centering and adaptive cruise control constantly. I am a fan. But not in bad weather.
