You may not drive around a multi-million dollar racecar or have a full time pit crew feeding you real-time telemetry info. But, you may someday be watching a F1 race while a special someone in your life is telling you to take out the trash. In either case, "leavemealoneiknowwhatimdoing" will serve you well. Er... wait, reality check. You can't say it out loud or you'll be in the doghouse. Wear the shirt and communicate in silence instead.
