What is the primary difference between a road course and an oval racetrack?

The primary difference between a road course and an oval racetrack is that road courses feature varied turns and elevations. Road courses are designed with a series of sharp and sweeping turns, elevation changes, and often include a mix of straight sections and curves, which challenge drivers to use a range of racing techniques. This complexity contrasts sharply with oval tracks, which typically consist of elongated, circular layouts that favor speed on straights and uniformity in turn shapes.

In addition, the multi-directional nature of road courses requires drivers to demonstrate versatility in handling, as they must adapt to the different corner geometries and slopes throughout the course. This aspect makes road racing distinctive, focusing on technical skill as much as on sheer speed.
