World champion Max Verstappen has hit out against the idea of a cap on Formula 1 driver salaries, arguing it would limit their ability to capitalize on the sport’s growing popularity and booming income.

F1 introduced a general cost cap last season for the first time in its history, but it excludes the three highest paid members of staff — typically the drivers and team principal.

Expanding expenditure controls to the drivers has long been mooted, with $30 million to cover a roster of two drivers informally proposed in 2020. The sport has yet to pursue it vigorously, with the question of how to deal with drivers already signed up on hefty salaries proving a tricky one to tackle, but the dramatic rise in inflation and ensuing spending squeeze has resharpened focus on its introduction in recent weeks.
