For the Road Warriors: Why are Burnouts in Drive a Bad Idea?

Last time my car saw the track I had to pull through the water box at a 1/8 mile track I had not visited in 5 years and did 2-3 operation. I got chastised by the starter on the line telling me my 1st gear only burnout was a danger! What an idiot! I proceeded to rip a 7.36 on Pro-Track street tires with cast iron full stock exhaust. They would not allow me to run again. My only guess was they did not want a Mopar to win the street legal only race sponsored by the local bow tie dealer that night! Was asked by many afterwards why only one run, told them to ask the track officials and left. No more of that and a fully restored car that only gets a tire spin in the driveway today.
