Operating an engine upside down causes oil starvation. Blue exhaust smoke will occur from oil submerging the cylinders, and the engine bearings could fail.
When cornering with a keyboard, repeatedly tap [action=steer_left] or [action=steer_right] to better control the steering angle and prevent unwanted understeer.
Many vehicles are not suited for spirited driving or racing in stock form. Aftermarket upgrades are available in the Parts Selector [action=parts_selector].
