The cars rev to full song, the drivers left leg twitches in anticipation of the start, not knowing exactly when the light will turn. A lot of questions go through the drivers' minds. For the drivers, it is a pressure packed few moments. For the fans, it is pure delight. When the light turns, the drivers engage the clutch.
Engines scream, tires squeal, and if they get it right, they rocket away down to the first turn.
Get it wrong and you pay dearly. Rolling starts have been a part of American motorsports for what seems like eternity. It thinks maybe it has to be an IRL, because the IRL has the Indy 500. I am not the first one to propose this, but I do think maybe its an idea whose time has come. As I stood in the pits at the US 500 for qualifying I watched as each driver pulled forward in line when it was time for their run.
