Dumbest newbie thing,you did at the drag strip.....
One at the strip but it really wasn't an accident. One of my cars liked to jam in reverse, backed into the burnout box and the car wouldn't come out of gear. The only way to get it out was to rev the engine up a bit and bump the clutch. People around and in the stands thought I was doing a burnout on reverse. Put it in 3rd gear and hazed the tires.
The other was at a street race. Knew I had the guy covered. The car had an electric fuel pump on it but the regulator was all messed up. Wouldn't keep the pressure below ~10psi. It would make the car load up if it ran to long down low. My friend tells me three or four times to turn it on, said after the burnout and I'm staging I'll flip it on. Well, I FORGOT. The guy starting the race said he was going to run across my lane to get out of the way, I put the other guy out 5 cars and told him not a good idea... Well, he got hit, broke his foot getting clocked by the bumper. I'm way out and the car lays down around 1000'... Lost! Then I saw a car pull out in front of us a little ways down the street. If I had turned the pump on and legged it out, I probably would have nailed the car pulling out. Best money I ever lost. I never raced on a street that had any side streets ever again.
