I'm seeing that car looks like accelerating after a hard U-turn drift even when i'm not pressing W. It's noticeable when you put settings to Drift: 30, Handling: 0, then driving a car with nuclear fuel.
Accelerate to full speed then let go of W and suddenly turn 180 degrees.
I guess it works as intended as far as vanilla mechanics is concerned, but physics would cause significant drag to the vehicle and almost act as breaking.
