There was a wreck up ahead, and two tow trucks with their emergency lights flashing were blocking the left two lanes. Traffic was stop-and-go due to the existing wreck. I was traveling in the lane to the right of the tow trucks as I approached. I stopped about 1–2 car lengths behind them. When traffic started to move, I began to move forward and advanced about a car length when the automatic emergency braking (AEB) activated and slammed on the brakes, even though the path in front of me was clear. The person behind me rear-ended me. Luckily, no one was physically hurt, but there is damage to our car that now has to be repaired, along with all the headache that brings.
