First of all, I should have said that these pics are not subject for guessing for you. All the guesses are correct but lets see can you tell which race the Countach was used or the first safety car was based on what car.
Rainmasters have their on and off days too, the only rainmaster that I think have never suffer any problems was Gilles Villeneuve.
Ayrton Senna have some excellent performances like Monaco 84', Estoril 85', Adelaide 91', Donington 93' but then he also have some off races too like the race in 89' and Spa 92'.
Michal have some excellent wet performances like Spa 92', Spa 95', Barcelona 96', Monaco 97', Sepang 2001, China 2006, Canada 2011, but he has bad races too like Spa 98', Interlagos 2003, Hunagaroring 2006.
Alonso has good performances like Interlagos 2003(despite the shunt), Korea 2010, Silverstone 2011, Sepang 2012 but also has bad perfromances like Hungaroring 2006, China 2006, Fuji 2007. Can't say anything about Canada 2011 as he was taken out by Button.
Hamilton has good performances like Fuji 2007 (despite the mistake), Monaco 2008, Spa 2008, Silverstone 2008, Monza 2008, Korea 2010, Silverstone 2011, Sepang 2012 but had bad performances like Nurburgring 2007, Interlagos 2008( he almost lost the title), Hungaroring 2011, Canada 2011.
Vettel has good performances like Fuji 2007 (Although crash out because of Hamilton's mistake), Monza 2008, Monaco 2008, Spa 2008, Interlagos 2008, China 2009, Korea 2010 (Despite engine blowup), Canada 2011, Hungaroring 2011, Sepang 2012 and bad performances like Silverstone 2008, Sepang 2009.
As far as I think, it is all related with the rules that FIA are implementing nowadays specially the Parc Ferme rules which clearly prohibit teams from changing the setups in the first place if the weather is different what has been anticipated at the time of qualifying. FIA should drop this parc ferme rules altogether so that the teams could change the setup overnight rather then last minute changes on the grid. Interlagos 2009 qualifying is a good example, the condition were torrential and teams that have opted for dry setup started from the back of the grid including Vettel, Button and Hamilton. While drivers that have gone for a wet setup have started from the front.
