Huh, odd. I have a car with assistive controls and they also tried to talk me into this warranty but I declined. They mentioned replacement would require extra money.

I did end up getting a windshield replacement shortly after purchase (like 6 months into ownership a rock came out of a truck and hit my windshield). I got it replaced for the normal $100-$200 not from the dealership and the vision system has had no issues.
