"No Hesi" refers to a community-driven approach to racing in Assetto Corsa, where players agree to drive without any form of assistance or hesitation. This means turning off features like traction control, stability control, and anti-lock braking systems (ABS), which are typically available in the game. The rationale behind No Hesi is to return to the raw, unfiltered experience of racing, where the driver is entirely responsible for the car's behavior on the track. This approach not only demands a higher level of driving skill but also fosters a deeper connection between the driver and the vehicle.
