The wheels aren't spinning without traction, that results in a terrible 0-60 time. Rollout originated from the practical reality of measuring with a starting beam - the tire doesn't stop breaking the beam until after it's started moving. With modern GPS data loggers and other corrections the use of rollout is just to lie about the 0-60 time to make it seem better than it is. Like the Model S Plaid wouldn't get to claim a 0-60 of under 2 seconds without that cheat code.
