Engines do not produce linear power. A realistic script uses a lookup table:
The most sophisticated part of any realistic driving script isn't the engine—it's the tire friction model. You borrow from Pacejka’s "Magic Formula." At low slip angles, the tire grips like glue. But the moment the lateral force exceeds the vertical load? The script must smoothly transition from static friction to kinetic friction —otherwise known as "the slide." realistic car driving script
