Rare Oscar Piastri trait highlighted after 'cheeky' McLaren demand

Martin Brundle believes "silent Aussie assassin" Oscar Piastri showed his "angry" side following the controversial penalty at the British Grand Prix.

Piastri lost the victory at Silverstone after being handed a 10-second time penalty for a safety car infringement in stamping on the brakes whilst preparing for the restart, with the stewards deeming this erratic driving.

The Australian ultimately lost the lead to team-mate Lando Norris after he served the penalty at his final pit-stop, and was bemused post-race at the penalty.

He had also asked McLaren if it would consider swapping the positions around after serving the penalty, one of a pair of traits Sky Sports F1 commentator Brundle noted in his post-race column.

"Unfortunately for [Oscar], he was in a brake-warming phase, but even so, he shed 100mph in that moment, and he breached rule 55.15 of the Sporting Regulations regarding erratic braking or manoeuvres," Brundle wrote in his column.

"This is a very important rule as the concertina effect, especially in poor visibility, can cause significant incidents in a ripple effect through the rest of the queue behind the Safety Car. As indeed it very nearly did.

The question was the scale of penalty for a clear breach.

"Ten seconds would be the standard issue unless there were mitigating circumstances to make it five seconds. But the stewards decided not given the extent of brake pressure and speed reduction in the car data.

"It is the first time we've seen the angry side of the calm, silent Aussie assassin. 

"Oscar's radio call for the places to be swapped if the team thought he'd received an unfair penalty was more than cheeky, though."
