A penalty that causes no inconvenience isn't a penalty. I though the point was to make drivers worse off than if they hadn't tried cheating in the first place. That way they wouldn't be tempted to get unfair advantage, because getting caught would mean being in a worse position than driving within the rules. Now the stewards are saying you might as well give it a go, as you won't actually be punished for it.
I wonder what Toto is going to say, because last time it was "the stewards found it a racing incident, just one of those things, no one at fault". This time the stewards found Rosberg publicly guilty of crashing into his team mate to drive him off the track, gave him a meaningless punishment that at least publicly acknowledged his cheating behaviour.
