Well, actually, there's a few that can. There's one guy here who built one of the outright record holding Pike's Peak cars for Monster Tajima. Other's have been paid professional drivers by manufacturers. Others have worked for motorsport preparation and fabrication companies. Some have done more than one of the previous.
I've tried to help him strive to be better. (See earlier this thread.) But he couldn't be told. That's fine. I ceased being interested back then.
Mitch (as well as a bunch of others in here...) needs to learn when to let go and move on. Believe me, others have been "spoken" to as well.
He also needs to occasionally listen to others instead of running the "I race Supercars and I therefore know better than you" line.
I admitted earlier I was wrong about one of my posts, and I retacted that.
I believe that we can ALL learn from each other. There is not always a right and wrong way. Sometimes saying nothing is better than saying something, too.
