But Did You Die Moment
At his very first autocross event, Anthony got a little too enthusiastic after crossing the finish line—keeping the throttle wide open before slamming the brakes at the last second to avoid a porta-potty… that someone was inside. The driver was fine, the spectator survived, and Anthony learned an important lesson about braking zones.
