Well then, let's set a challenge people might enjoy.
Spa-Francorchamps want to expand the 24 Hours of Spa into a rival of the Le Mans 24 Hours. Extend the current Grand Prix circuit along the old massive track to make a Le Mans Circuit de la Sarthe style extended layout. Make sure it's suitable for modern race cars, with the longest flat-out stretch being no longer than 2.1km. Try to follow the old layout as best as possible.
