Jarno Trulli believes the high degradation of Pirelli's tyres will lead to confusion in the races this season
With at least three pitstops per driver expected in the opening races, the Italian fears the amount of stops will make the races too confusing for the spectators.
Trulli also denied drivers had asked for the tyres to degrade so fast, but he is hopeful the FIA and Pirelli will work to rectify the situation.
"Speaking with the other drivers, I've noticed that everyone bar none has had big problems with tyre degradation," Trulli wrote in his column for Repubblica newspaper.
"After just five laps the tyres lose a good part of their efficiency. The most balanced cars can reach seven laps, but after that it's a vertical drop. A driver can do 14 laps to finish his run, but with no performance.
"This is why we have complained: it's not true, as I've read in some places, that we asked for tyres that degrade so quickly. We've never asked for any such thing, also because for a driver tyre consistency is a fundamental element.
"It's what allows you to evaluate all the other set-up variables. If the tyres are inconsistent you never really understand what makes your performance better or worse.
"The tyres' high degradation will also cause great confusion in the race, with at least three pitstops for each car. That's an average of 72 pitstops per race: a hardly manageable situation. The Federation has taken notice, and so has Pirelli.
"No one wants to leave the race in the hands of such a random variable. Pitstops are random elements that are too difficult to manage, therefore I hope the situation may improve on Sunday already."
OPINION: Max Verstappen is back in the lead of the 2021 Formula 1 drivers’ championship, with the season’s final flyaway events set to get underway in the USA this weekend. But a defensive stance he’s recently adopted could have a lasting impact for the Red Bull driver when it comes to his chances of defeating Lewis Hamilton and Mercedes
Despite appearing to adjust to life as a Ferrari driver with relative ease, it was far from straightforward under the surface for Carlos Sainz Jr. But, having made breakthroughs in rather different routes at the Russian and Turkish races, he’s now targeting even greater feats for the rest of the Formula 1 season
Emerson Fittipaldi is better remembered for his Formula 1 world championships and Indianapolis 500 successes than for the spell running his eponymous F1 team. Despite a hugely talented roll call of staff, it was a period of internal strife, limited funding and few results - as remembered by Autosport's technical consultant
In the 1960s and 1970s, McLaren juggled works entries in F1, sportscars and the Indy 500 while building cars for F3 and F2. Now it’s returning to its roots, expanding into IndyCars and Extreme E while continuing its F1 renaissance. There’s talk of Formula E and WEC entries too. But is this all too much, too soon? STUART CODLING talks to the man in charge
Yuki Tsunoda arrived in grand prix racing amid a whirlwind of hype, which only increased after his first race impressed the biggest wigs in Formula 1. His road since has been rocky and crash-filled, and OLEG KARPOV asks why Red Bull maintains faith in a driver who admits he isn’t really that big a fan of F1?
OPINION: After Lewis Hamilton responded to reports labelling him 'furious' with Mercedes following his heated exchanges over team radio during the Russian Grand Prix, it provided a snapshot on how Formula 1 broadcasting radio snippets can both illuminate and misrepresent the true situation
OPINION: Valtteri Bottas is credited with pole position for the 2021 Turkish Grand Prix, despite being beaten in qualifying. This is another example of Formula 1 and the FIA scoring an own goal by forgetting what makes motorsport magic, with the Istanbul race winner also a victim of this in the championship’s recent history
