Formula 1's debate over common ownership structures has intensified following Zak Brown's letter to FIA president Mohammed Ben Sulayem. McLaren's CEO raised concerns about potential unsporting cooperation between Red Bull Racing and its sister team, citing shorter gardening leave periods and possible intellectual property transfers that could provide unfair advantages.

The controversy stems from specific incidents including Daniel Ricciardo's suspicious fastest lap in Singapore, where the Racing Bulls driver pitted late to steal points from Lando Norris's championship challenge. Similarly, Racing Bulls instructed Liam Lawson to let Max Verstappen through during the Miami GP, sparking immediate debate about coordinated tactics.

However, recent races show Racing Bulls drivers actively competing against their sister team. In Japan, Arvid Lindblad aggressively defended against Isack Hadjar, forcing him onto the grass and earning warnings. The rookie made Hadjar work for every position while also battling Verstappen hard in China, demonstrating genuine on-track rivalry rather than cooperation.

Laurent Mekies defended the arrangement by pointing to strict FIA regulations and self-imposed longer gardening leave periods. His challenge to examine on-track battles throughout the season reveals that Racing Bulls drivers consistently compete independently, undermining claims of systematic bias.
