What happened: Sergio Perez was stripped of a 10th-place finish at the Monaco Grand Prix after FIA stewards issued a post-race 10-second time penalty. The Cadillac F1 driver was found to have his front-right wheel outside the starting box during a critical late-race standing restart. The ruling demoted Perez to 15th, handing the final point-scoring position to Aston Martin's Fernando Alonso.

Why it matters: The penalty marks a major setback for Cadillac F1, which was on the verge of its first-ever Formula 1 point in only its sixth race. By inheriting P10, Fernando Alonso secured Aston Martin's first point of the 2026 season, allowing the team to move ahead of Cadillac in the Constructors' Championship. The decision underscores the high stakes of the 2026 regulations as teams fight for narrow mid-field gains.

What to watch: Formula 1 heads to the Canadian Grand Prix next, where Cadillac will look to rebound and find the scoreboard. The stewards' busy weekend in Monaco may prompt further discussions on restart positioning in upcoming briefings.
