Villeneuve is now twelve seconds ahead of Villeneuve.
The lead car is unique, except for the one behind it which is identical.
Now he must not go the wrong way round the circuit, and unless he can spin himself stationary through 360 degrees I fail to see how he can avoid doing so.
Alboreto has dropped back up to fifth place.
We now have exactly the same situation as we had at the start of the race, only exactly the opposite.
I can't imagine what kind of problem Senna has. I imagine it must be some sort of grip problem.
