No single event or series is ever going to answer that question properly, but the annual Race of Champions at least does a good job of choosing the most talented drivers in their respective disciplines and lining them up against each other and the clock.

Scroll down for two videos, one short recap and one full three-hour-long version.
Come back later today at 7:00 PM EST to see who's crowned the Champion of Champions during individual events!
