I was reading about the history of Indycar, and came across the USAC National Championship Trail which between 1956-1970 had rounds that involved Road Races, Paved Ovals, Dirt Ovals and Hill Climbs. This made me think if such a championship would be possible these days, which could involve different disciplines such as races, time trials, asphalt, dirt, road courses, street circuits, ovals, sprint races, endurance races, etc.
