Pit stops are a part of racing.
Let's imagine this scenario at Abu Dhabi - Piastri leads and is in position to take the WDC, comes in to pit, the stop is slow resulting in Norris taking track position and the WDC lead.
I don't for a single second think that Mclaren would ask Norris to let Oscar by for the WDC, not a chance.
It's blatant favouritsm and a collossal cock up by the team. Norris wanted to go 2nd, it was his call to gamble on a red flag or a safety car, there wasn't any threat from Leclerc on Piastri and even if there was, why would Norris care.
Also if one of the cars has a mechanical failure, that's a cock up by the team as well, is it not? Would the other driver then be required to put it in the wall out of solidarity and fairness?
