The pitlane has dozens, maybe hundreds of people potentially in the way of a run away tire. Out on track there is safety fences, tire walls, etc. There is supposed to be no one effectively in danger out on the track, in the pits there are loads more people that have to be there. The pit lane has significantly more people in danger than any other place out on track so yes, the rules and penalties should be harsher.
Riccy's tire could have come off and hit an entire pit crew, with bad luck it could have hit a couple pit crews and hit a team on the pit wall. Maldonado hit Guti and there was no risk of other people being hurt.
Rubbish. I understand the potential of severe incidents in the pitlane, but causing yet another accident through incompetence and/or rage is far more damaging to a race event than leaving your pit with a wobbly wheel. What your suggesting is that anything that happens in the pit lane is automatically more severe than anything that happens on track due to there being more people about. Should doing 81km/h in the pitlane be handed a more severe penalty than speeding through double waved yellows with marshals about on track?
Both the incidents need to have been punished, but the randomness of the penalties is unbalanced. Ricciardos 'crime' is not twice as severe as Maldonados.
