Oscar Piastri has had a scare in first-day practice at the Italian Grand Prix, avoiding a potential grid penalty and escaping with a reprimand after a pit-lane incident at Monza.
Australia's F1 world championship leader was investigated by stewards after failing to follow the race director's instructions, having left his pit box before being given the all-clear following a red flag period during Friday afternoon's second practice session.
Piastri ended up with just a reprimand and ended the afternoon, declaring it had been a "good day" after he finished fourth quickest in the second session, even though his McLaren teammate and main championship rival Lando Norris went fastest.
