I was traveling early morning before sunrise over the tehachapi pass towards Mojave in California. Someone had lost a camper shell from the top of a pickup truck in the lane. It was still dark outside. I saw the obstruction in the road but the car cameras did not pick it up. I pulled into the left lane to try to get around the camper shell. The lane assist pulled me right back into the camper shell which tore down the side of the car doing 10k in damage. The car never recognized impact or an accident. I have the videos from the cameras of the car. The lane assist, as far as I know, only doesnât activate when the turn signal is used, which I did not have time for, as I had less than 200 feet between me and the camper shell.
