I was driving my 2020 subaru forester sport in the left lane along an on-ramp to the highway, which consists of a road that curves to the right. there was snow on the ground but the roads were clear and dry. suddenly and in a matter of a few seconds, the car began to beep continuously while the steering wheel veered to the left and locked, and the anti-lock brake system kicked in as i tried to correct the wheel and brake the car. i was suddenly completely out of control of the vehicle as the car drove me off the road and down into the snowy median, where it rolled at least once before landing upright. i believe the error with the car may have occurred with subaru's brand-new lane centering technology, released with the 2020 edition vehicles. the technology will physically direct the steering wheel towards the center of the lane if it detects the vehicle is getting too close to either lane line. lane centering is a feature of the subaru's driver assist technology, called eyesight. i'm unsure if the malfunction occurred with eyesight or with the lane centering function specifically.
