I think that it's going to be like that, single-file. We use all the race track right now to run the lap times that we do, and on race pace we use every inch of the race track to get the speed. ... It was easier to run side-by-side because you didn't need that extra track. Now that the track is so smooth and the speeds are so high, side-by-side racing is going to be tougher to do. And we just won't see as much of it.
