With track temperatures rising to 47°c, the tyre companies were suffering with extensive graining with their rubber after failing to predict such extreme conditions, and as bits and pieces were chewed off, the track rapidly became an ice rink off line.
The tight hairpin was a perfect example. With drivers braking from 300kph to 50kph for the tight right-hander, the balls of excess rubber slowly accumulated on the exit of the turn, leaving a thin line in which to take the corner safely. Kimi Raikkonen would later lose second place to Michael Schumacher after running wide onto the marbles on the penultimate lap.

However, it was those marbles - plus a helping hand from Ralf Schumacher - that brought the eventual downfall of Jacques Villeneuve. Schumacher had been struggling with his TF106 all afternoon having selected the hard Bridgestone tyre, and after numerous spins, was out of contention for points.
Villeneuve, who was chasing a top-six finish, came upon the stricken Toyota in turn five and Ralf, thinking he was helping out, suddenly slowed on the apex of the sweeping right hander. However, by pulling out onto the marbles to get by, the Canadian's BMW Sauber just careered straight into the outside wall.
"Ralf Schumacher was running very slowly for quite a few laps," fumes Villeneuve. "When he decided to let me by it was through a corner. He lifted and just to avoid him I had to go wide where there was old rubber from the tyres - it was like being on an ice rink."

"This is always a tough race and sometimes it doesn't work out," he added, though for Villeneuve, it never works out as his last points score on his home circuit, which is also named after his late father, now dates back to 1996.
Ralf Schumacher admitted to having struggled throughout the race after selecting the harder Bridgestone compound, leaving him without grip for the entire race. "There was no specific problem but I just couldn't find any grip out there.," he admitted.
"It was my mistake because I went for the wrong tyres," he added. "It was a tough race for everyone because there were so many marbles out on the circuit every time I went on them with my hard tyres I'd lose control of the car."
