#2 Giancarlo Fisichella wins bizarre Brazil Grand Prix (2003)
If you want to talk about chaos at Interlagos, the 2003 Brazilian Grand Prix would be the best example of it.
A race held in pathetic conditions, such a start would never have been allowed in this day and age, but back in 2003, the field lined up anyway. Drivers crashed out one by one, until the field narrowed down to a select few.
Towards the end, Giancarlo Fisichella and Kimi Raikkonen were left fighting it out to decide the winner, but two laps from the end, the race was stopped. Mark Webber had crashed into the barricade and while his debris lay in the middle of the track, Fernando Alonso came and smashed into it, causing all sorts of mayhem.
Raikkonen was initially declared the winner of the race and handed the trophy, but was forced to hand it over to Fisichella at San Marino next time out after it was adjudged that he was the real winner.
