Should qualifying have gone ahead in Brazil?
Qualifying for the Brazilian Grand Prix proved to be the most challenging of the season with heavy rain at Interlagos playing havoc with proceedings.
Drivers found themselves struggling for grip on a circuit that was under standing water in places, while Force India driver Tonio Liuzzi suffered a heavy crash at turn one after aquaplaning off the track approaching the braking zone.
The conditions also saw Sebastian Vettel's slim title hopes take a hit when he fell at the first hurdle in the session - along with defending champion Lewis Hamilton.
With lengthy stoppages and widespread confusion about exactly when - and if - the session would restart during the numerous stoppages, it begged the question over whether qualifying should have even taken place considering how much rain was coming down.
