Pro Driver Is Insulted After Giving Advice To Game Developer

If you’re the boss of a company that makes a racing simulator that claims to offer ‘a highly realistic driving experience’ with an ‘advanced physics engine’, you’d think getting free advice from a professional driver would be a good thing.

But when Fredrik Sorlie – movie stunt driver, the man who drifted the Nurburgring, and professional instructor for the likes of Porsche and BMW – offered some advice on how the tyres work in Assetto Corsa, one of the developers was unimpressed. Big time.

Sorlie complained that the street tyres understeered too much when the brakes came off on turn-in, while adding light throttle in a turn would immediately cause a car to oversteer. In ‘real life’, easing off the brakes on turn-in is a technique used by racing drivers to keep the weight balance in check and keep grip on the front wheels as they turn, while touching the throttle mid-corner pushes the rear down and improves grip.

To his credit, the Norwegian was totally polite and explained his issues in detail, even tweaking the game’s code to find a solution and running it by other professional driving friends to get their opinion.


Unfortunately, Stefano Casillo, developer at Assetto Corsa-maker Kunos Simulazioni, didn’t take the advice very well. Sorlie has revealed that he was insulted by Casillo during a private exchange on the game’s forum, because he clearly didn’t believe that the driver’s input was in any way relevant.

Over the course of the conversation, Casillo calls Sorlie ‘ignorant’ and tells him to ‘OPEN A ***ING BOOK AND READ’. He also says that the man who makes a living driving at the limit doesn’t have a clue how tyres work.


Casillo’s beef seems to stem from the fact that the cold, hard data he works with contradicts what Sorlie says, and therefore dismisses his opinion.

However, Sorlie gets the final say on his solution to fixing what he ‘feels’ is wrong.

I did not claim it was realistic, just that for now it’s the least intrusive alternative. A compromise, if you will. For me, anyway. And for the Australian touring car champion. And the European drifting champion. You know, just some friends who have no clue about how tyres work.
