Whatever your position on Nico Rosberg's suspicious trip up the Mirabeau escape road in the final minute of qualifying for the Monaco Grand Prix, you will agree that it was unfortunate for those behind him - and that wasn't only Lewis Hamilton - who lost out on what would have been their key qualifying laps.
A badly-timed yellow flag is an inherent risk in motorsport, particularly in qualifying. At a tight track like Monaco, drivers will always face the danger that when their tyres are at their best and they embark on what should be the ultimate lap, someone else will make an error and ruin everything.
This situation is unavoidable. No matter what action is taken, it's impossible to give a driver back a lap that they had to abandon. There is no way to cancel out the consequences.
