No it brakes when a semi changes lanes and appears IN FRONT of my truck and I am accelerating upon it. Not when there is a vehicle next to my truck. It senses the full 18 wheeler as wall and will decelerate rapidly pretty normal to me. The ACC works well and did 3600 mile road trip in 2021
So I have an 18 play with all these options. Did a road trip from WAshington to Colorado and experienced the same thing with the dynamic cruise control. Whenever a truck would be in front of me, even 10-20 car lengths truck would brake hard, I think the sensors thinks it a wall I’m driving into...
