Just changed from Normalto Simulation, etc and I am still finding cars to under steer like mad. It's literally un-driveable. I've driven/competed on Circuits, Hill climbs, Sprints and never noticed any of the cars I've driven like it. 80mph Under-steer out of a corner in a Ferrari 458? The Scooby is also atrocious for this. Ruined it for me tbh.
You must be doing something very wrong
