The thing is, how would you determine what is/is not a safety reason? And it would be unfair to a driver who has a pit stop sized lead but whose tires only have a couple of laps life left in them!
IIRC at some point in the distant past teams were not allowed to change tyres under a red flag but it led to incidents due to drivers trying to avoid a pit stop on worn/incorrect tyres so the rule was scrapped.
Leclerc was unlucky due to weak strategy (again) from Ferrari. Perez was a deserving winner being the better of the two Red Bulls that weekend Also good to see Russel keep up his feat of a top 5 position at every race this season.
Really Ferrari could do with IMO poaching a couple of strategy people from elsewhere in the pitlane, e.g.
Bernadette Collins, because whoever is/was doing it for the past few years hasn't learnt from their past mistakes.
Russell's certainly a consistent point scorer now that he's in a halfway decent car. Any doubts Toto Wolf
might have had over signing him after his
faux pas in Imola last year must be long gone.
That would be something for the FIA to worry about and oversee just as they do with bodywork changes.
While the FIA got it more or less right with this years aero rules, it does seem like they could use a hand with race direction after the chaos yesterday over start time and tyres. Credit where it's due, at least we now know that the white line
is the edge of the track! - only taken a few decades to sort that one...
