Caporegime
The Arnoux Villeneuve battle would never happen again because those drivers gave a cars width, respect because locking wheels would easily kill you. As you saw with Massa on Hamilton at the start of the GP the only defensive driving these gimps know is to cut the road off or edge over in the hope thge other driver yeilds or ends up on the grass.
More to the point, slip-streaming was a bigger effect than the effect of dirty-air on aero. They were able to pull passing moves because the guy behind had the advantage.
