Martin Brundle believes the increasingly demanding Formula 1 calendar could be contributing to the technical failures and operational mistakes witnessed during the recent Grands Prix in Malaysia and Singapore. The former F1 driver and television commentator has raised concerns about fatigue among those responsible for running the championship, suggesting that the relentless schedule may be placing additional pressure on systems and personnel.
Two particularly notable incidents have brought those concerns into focus. Heavy rain at Sepang exposed an unexpected software problem that required an emergency correction, while Singapore Sprint Qualifying was affected by a Race Control mistake involving Overtake Mode. For Brundle, these episodes, together with other recent technical irregularities, suggest a wider issue involving the demands placed on Formula 1’s organisation.
Martin Brundle questions whether F1’s demanding calendar is increasing errors
Brundle identified fatigue as a possible explanation for the problems emerging during consecutive race weekends. His concern centres on the intensity of the championship’s schedule, which he described as involving six races across seven weekends and nine events within an eleven-week period.
Such a demanding programme requires Formula 1 personnel to move repeatedly between circuits, often working within temporary facilities established specifically for each event. Brundle pointed to Singapore as an example of the environments in which the championship must operate, with infrastructure assembled around existing concrete and asphalt surfaces.
In his view, this constant movement and the pressure of delivering successive Grands Prix could be affecting the people and systems responsible for ensuring that events run correctly. Although he did not establish fatigue as the definitive cause of the recent incidents, he considered it a possible contributing factor.
The concern is particularly significant because Formula 1 depends on close coordination between teams, officials and technical systems. Even relatively small operational mistakes can create complications when sessions are interrupted or procedures need to be changed at short notice.
The wider demands of the season are reflected in the 2026 Formula 1 calendar, which requires the championship to operate across numerous international venues throughout the year.
Sepang software failure exposed unexpected F1 technical vulnerability
One of the incidents highlighted by Martin Brundle occurred during the rain-affected Grand Prix weekend at Sepang, Malaysia. Difficult weather conditions triggered an unexpected software malfunction, forcing Formula 1 officials and teams to find a solution before racing could proceed.
Brundle explained that the underlying issue had appeared in a specific sector of the circuit where a problem had not been anticipated. He acknowledged that the situation should not have occurred, but noted that those responsible identified the difficulty and developed a software correction relatively quickly.
Once the solution was prepared, the teams installed the updated software on their cars, allowing the race to go ahead. However, the process was not completed simultaneously across the field.
According to the former driver, one team required additional time to obtain approval from its headquarters before implementing the correction. That delay added another ten minutes to proceedings, although Brundle deliberately chose not to identify the team concerned.
The episode illustrated how an unforeseen technical fault can create additional complications when teams and officials must react under time pressure. The circumstances surrounding the incident, including the Sepang software problem during wet conditions, also demonstrated the importance of finding a workable solution before the event could continue.
Singapore Overtake Mode mistake adds to Race Control concerns
Formula 1 encountered another problem at Marina Bay, this time involving a human error during Singapore Grand Prix Sprint Qualifying.
The incident followed a red flag caused by Sergio Pérez’s accident at Turn 5. When the session resumed, Race Control failed to reactivate Overtake Mode, leaving the system unavailable despite the return to green-flag running.
Unlike the unexpected software malfunction in Malaysia, the Singapore issue involved an operational mistake. Both incidents nevertheless contributed to the discussion about whether Formula 1’s increasingly demanding schedule is placing excessive pressure on the personnel responsible for managing these procedures.
The FIA’s acknowledgement of the Singapore Overtake Mode error brought particular attention to Race Control’s responsibilities during session interruptions. The failure occurred at a point when drivers and teams were attempting to complete competitive laps following the red flag.
For Brundle, the sequence of problems across Malaysia and Singapore raised questions extending beyond any single malfunction. His concerns involved the broader reliability of the processes needed to operate modern Formula 1 weekends.
Timing systems and onboard data also raise questions
The former Formula 1 driver also referred to other unusual problems encountered during recent Sprint Qualifying sessions, stressing that not every difficulty could be attributed exclusively to the FIA.
He identified irregularities involving onboard cameras, driver-tracking systems, lap times, sector times and telemetry information. These different systems form part of the technical infrastructure used to follow and manage Formula 1 sessions.
Brundle considered the accumulation of such incidents unusual, particularly in a championship where technical accuracy and operational reliability are expected to meet exceptionally high standards.
The Singapore weekend had already demonstrated how several separate difficulties could emerge during the same qualifying session. Alongside the Overtake Mode mistake, the event experienced a distinct timing-system problem, further complicating an already interrupted session.
Further details of the governing body’s response to the Singapore Sprint Qualifying errors and subsequent FIA explanation illustrate the nature of the operational difficulties encountered at Marina Bay.
Why Martin Brundle believes F1 must avoid repeated operational mistakes
Brundle’s central argument is that Formula 1 may be placing its personnel and technical infrastructure under more pressure than they can comfortably absorb throughout such an intensive sequence of events.
He suggested that fatigue could help explain why unexpected software issues, procedural mistakes and irregularities involving technical information have appeared within a relatively short period. However, his comments stopped short of establishing a direct causal connection between the calendar and every individual problem.
The former driver also emphasised that such difficulties should not be considered acceptable simply because Formula 1 operates in demanding circumstances. The championship’s status and technical sophistication create an expectation that its systems should function reliably even under significant operational pressure.
With the recent incidents in Malaysia and Singapore providing several examples of what can go wrong, Brundle’s observations raise a broader question about the workload facing Formula 1 personnel and whether the sport’s demanding calendar is beginning to affect the precision required to run race weekends successfully.
