I used the wrong word. It's only dangerous if you do it at a traffic light where you increase your chance of getting into an accident. Street drag racing is both dangerous and juvenile. Jack rabbit starts are not good for the longevity of your car. They place high stresses on the drive train which can result in early failure of the transmission, differential, CV joints and other associated parts. It also wears out your front tire tread rapidly while giving the local police an opportuniy to write you a citation for speeding and, or reckless driving.How is it dangerous to accelerate quickly from a dead stop?
