I took part in a "gravel" WRC event in Paris last year, it was held on a temporary track using the Davic system and was tremendous fun. The surface was incredibly slippery and required very delicate control.
The track is sprinkled with Nesquik chocolate powder
You could pressure the car in front into a mistake by tailgating
The cars ran reliably all afternoon other than the occasional dusting down to shake out the excess powder.
