Abysmal conditions at the Belgian Grand Prix meant that no drivers set times in the second free practice session. Michael Schumacher, Jenson Button and tyre supplier Michelin have all suggested the race could not go ahead in similar weather.
It is two-and-a-half years since the last fully wet race – Interlagos 2003 – at which neither tyre company had suitable tyres for the drenched track. Since 1994 the pursuit of safer racing has caused some wet races to be started behind the safety car but no race has yet been cancelled due to adverse weather. Ironically, Schumacher had hoped for rain this weekend to equalise his car disadvantage.
