Short answer: The boos directed at Lando Norris in Mexico were widely reported as a reaction from some Mexican fans, likely tied to perceived favoritism toward Norris by his McLaren team and broader local sentiment around national pride and competition, rather than a personal attack on Norris himself. The exact reasons varied among observers, but coverage highlighted a subset of fans expressing disapproval during and after his Mexico City Grand Prix victory.

Details and context

• After Norris won the Mexico City Grand Prix, reports noted a notable portion of stadium fans cheering or booing, with analysts and commentators pointing to a mix of factors including perceived team favoritism, fan passion for local drivers, and the intense championship battles shaping expectations in Mexico.

• Media discussions in the wake of the race highlighted that Norris’s victory was celebrated by many, but the booing from some sections of the crowd was interpreted as disapproval of how Norris and McLaren were perceived to be treated or favored within the sport, rather than a straightforward anti-Norris sentiment.

• Broader reactions included explanations from pundits who argued that Mexico’s fans are highly vocal and deeply invested in the sport, sometimes expressing strong opinions about decisions they believe affect competitive balance or national pride in the Formula 1 scene.
