drag racing就这样
Rollout or rollout allowance in North-American drag racing is the difference between actual acceleration time and measured acceleration time. For the published 0 to 60 mph acceleration time in North America, a rolling start is used, beginning 1 foot (0.3 m) after the initial standing start position.
