“I was driving down the freeway driving at the speed of traffic. My vehicle started beeping aggressively, a red indicator started flashing over the frunk area of the vehicle representation in the dash and my vehicle entered red turtle mode. This red turtle mode severely reduced the vehicle's speed and ability to maneuver on the freeway. I was almost struck by numerous vehicles while attempting to get to the side of the road. I had been driving in the number 3 lane of a 5 lane freeway where lane 1 was an exit only offramp. Once I got to the side of the road, I power cycled the vehicle. …”
