Carlos Sainz wants a new rule to deter drivers from deliberately causing red flags in a qualifying session.
It is a tactic that is difficult to prove, but which has been suspected in Formula 1 for many years. It has been suggested that, on some occasions, drivers have been accused of setting a strong time and then crashing with the intention of ruining others' chances of beating them.
The subject has been brought into focus again by speculation in the wake of Max Verstappen's refusal to let Sergio Perez pass him at the Brazilian Grand Prix last weekend. Some reports have claimed it had something to do with the Mexican's crash in Monaco qualifying earlier this year which adversely affected his team-mate – a rumour Perez has denied.
