I think most of us who race probably drove like idiots before we hit the track;

My street bike exploits were numerous between 1978-1985 before taking to the track. Flung my 79 DT100 down the road while dragging the foot pegs........ok don't lean that far on trials tires...........flung my brothers KZ400 down the road....charged up to a stop sign on grabbed a handful of front brake........oops can't see that oil at night , the bike went sliding through the intersection with cars dodging it like mad. I came to an instant stop and had the wind knocked out of me. Showing off on my 12 second RD350 lost the front end at 50 MPH storming into a corner.........major road rash. I used to love to slide bikes into corners , on dry pavement , and while riding my lovely restored BSA 650 ran out of traction and low sided it........the gas cap poped open as it sparked down the road (never caught fire) SRX600 huge tank slapper over the bars at 80-85 MPH (screamed and no sound came out) thankfully I had leathers on for this one. Shortly after this I started racing.
I did lots of stupid stuff in cars before 1985 as well but got away with it..............after 20 years of racing I seldom drive over 75 mph....maybe 80 on lonely highways. Being a young male with a car is often deadly. I always respected guys who drove normally , as I myself didn't understand how lucky I was at the time to survive my antics.
