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

I did a 335 foot burnout in a 70 Coronet , 440/727 276 sure grip 275/60/15 Firestone Firehawks on blacktop in an apartment complex in Denver Colorado starting out in drive power braking and it shifted through all the gears roasting the tires so good the fire department showed up thinking the buildings were on fire until I rolled down the street on two flats with cords taking paint off the car. that trans was bone stock and never blinked an eye
Yheee hawww!!!!!!!!
