A four-car accident occurred at the high-speed Raidillo🍎n during෴ the opening hour of running at the Spa 24 Hours on Saturday, with four drivers requiring medical treatment.

Williams F1 reserve Jack Ai𒀰💛tken and Ferrari factory driver Davide Rigon were taken to hospital for further checks, while Kevin Estre and Franck Perera were given the all-clear after an initial assessment at the circuit’s medical centre.

Rigon was released from hospital on Saturday evening but Aitken, who was driving an Emil Frey ൲Lamborghini, remains in hospital with non-life-threatening injuries.

Two years ago, Anthoine Hubert lost his life in a horrific Formula 2 crash at the same corner in an accident that also left Jua🔯n Manuel Correa severely injured.

Alfa Romeo F1 reserve Ilott, who was also competing in the 2019🅘 F2 race, feels changes are required to prevent similar accidents in the future🐟.

“Therꦡe needs to be a change at this corner and I’m very surprised nothing has changed yet,” he wrote social media. “Enough is enough.”

“If I’m wrong for chasing for better safety after seeing four of my friends involved in massive acci൲dents then🦂 I may as well not be human.

“I’ve come back to Spa after 2019 and I will come back again after this. But that doesn’t mean if something isn’t good enough it shouldn’t be fi𒆙xed.”

In another rꦐeply to a Twitter user, Il🦄ott argued it is the “barrier mainly” which needs a revision.

Spa-Francorchamps will host F1’s Belgian Grand Prix on Au꧋gust 2🐼9.
