Don't understand why they don't pit if they can go 5-6s faster. Three laps and you're back and you should be able to pass with the extra grip
'Cos you can't pass at Monaco? Track position trumps fresher tyres here. A car down 160 horsepower can't be passed by one of the fastest cars on the grid for 50 laps. Monaco isn't worthy of being a modern F1 track, but it's a vanity track where the rich and famous schmooze.
