James Vowles has confirmed that Mercedes operated with a written and regularly updated set of racing guidelines during Lewis Hamilton’s time with the team, highlighting a clear difference with Ferrari’s current approach to managing its drivers. The subject has become particularly relevant after Hamilton questioned the absence of explicit rules at Maranello following his clash with Charles Leclerc at Monza.
Ferrari team principal Fred Vasseur does not believe a detailed rulebook is necessary, arguing that experienced drivers should already understand the principles expected of them. Vowles, however, has explained that Mercedes deliberately formalised those expectations and continued refining them when incidents exposed gaps in the system.
Lewis Hamilton raised Ferrari rules concern after Charles Leclerc clash
The debate followed a tense moment between Lewis Hamilton and Charles Leclerc at the first chicane in Monza. Hamilton attempted to pass his team-mate, but Charles Leclerc defended aggressively and forced the Briton into the gravel, costing him six positions.
Charles Leclerc later acknowledged that he had gone too far. The incident nevertheless raised the question of whether clearer instructions governing wheel-to-wheel racing between the two Ferrari drivers could have prevented the situation.
After the race, Lewis Hamilton contrasted Ferrari’s approach with the structure he had experienced at Mercedes. The seven-time world champion explained that his former team had operated with written rules of engagement, whereas Ferrari did not have an equivalent written framework.
The episode adds another dimension to the evolving relationship between the two team-mates and to Charles Leclerc’s influence within Ferrari as the team manages two highly experienced drivers with their own competitive priorities.
Ferrari removed Lewis Hamilton’s comments from media audio
Ferrari subsequently removed Hamilton’s remarks about the lack of written rules from an audio recording distributed to the media, suggesting that the comments had not been well received internally.
The question later resurfaced when James Vowles discussed the subject on Formula 1’s Beyond the Grid podcast. Before becoming Williams team principal, Vowles worked as Mercedes’ chief strategist and had direct responsibility for the system Hamilton had referenced.
He confirmed that Mercedes maintained a written document governing how its drivers should race one another. Internally, the team eventually referred to it as racing intent, although its underlying purpose remained the same as a set of rules of engagement.
James Vowles explains how Mercedes kept changing its driver rules
James Vowles explained that managing those guidelines was one of his responsibilities at Mercedes, joking that it was not literally his only task because he occasionally had to make coffee as well.
More importantly, the Williams boss acknowledged that the original system was not complete. He felt he had been naive about certain possibilities when developing the rules in 2014, and Mercedes consequently adjusted the document during the season whenever its drivers found situations that had not been properly covered.
That experience is central to the contrast with Ferrari. Rather than assuming every possible racing situation could be understood through general principles, Mercedes continued adapting its written framework as new problems emerged.
Lewis Hamilton’s broader adjustment to life at Maranello remains one of Ferrari’s major storylines, with the British driver continuing to compare his new environment with the methods he experienced during his years at Mercedes.

Lewis Hamilton and Nico Rosberg tested the Mercedes system
The need for such rules became particularly clear during the intense rivalry between Lewis Hamilton and Nico Rosberg. Their 2014 Belgian Grand Prix ended badly when the two Mercedes drivers made contact, with Hamilton eventually retiring because of the damage.
The 2015 season was comparatively calm between them, but further incidents followed in 2016. The team-mates eliminated each other in Barcelona and were each fined £360,000 to cover the repair costs.
That sanction did not prevent another collision later in the year at the Red Bull Ring. Hamilton went on to win in Austria, while Nico Rosberg received a 10-second penalty and finished fourth.
For James Vowles, those experiences showed why even a written document needed to evolve. The basic principles could be established in advance, but competitive drivers repeatedly created situations that required the team to clarify or adjust the framework.
Fred Vasseur believes Ferrari does not need explicit written rules
Fred Vasseur takes a different view of the situation at Ferrari despite the growing competitive tension between Lewis Hamilton and Charles Leclerc. The Ferrari team principal has rejected the suggestion that every possible on-track scenario should be covered by explicit rules.
Vasseur’s position is that attempting to include every potential situation in a contract or detailed document would inevitably lead to further interpretation. Disputes could simply shift towards questions over precise positioning on the circuit rather than being solved by the existence of another written clause.
Instead, the French manager believes the fundamental principles are already clear and that both drivers understand what Ferrari expects from them. The approach therefore places greater responsibility on Hamilton and Leclerc to interpret those principles correctly in the heat of competition.
The issue comes while Fred Vasseur’s leadership continues to attract wider scrutiny, although his stance on driver management remains clear: Ferrari does not need to replicate the detailed written framework Mercedes previously used.
Ferrari relies on the experience of Lewis Hamilton and Charles Leclerc
That position is also shaped by the enormous amount of experience inside Ferrari’s current driver pairing. Lewis Hamilton and Charles Leclerc have accumulated almost 600 Formula 1 races between them, leaving the Scuderia with two drivers who have spent years dealing with high-pressure racing situations.
The disagreement is therefore less about whether the drivers understand how to race and more about how much should be formally defined by the team. Hamilton’s experience at Mercedes showed him a system where expectations were written down and continually revised. Vasseur prefers a framework based on established principles and the judgement of his drivers.
After the Monza incident, that difference in philosophy has become much more visible. James Vowles’ account confirms that Hamilton’s comparison with Mercedes was rooted in a formal system he knew well, while Ferrari remains convinced that its own approach does not require the same level of written detail.
