Abstract
The present invention provides a race track configured to encourage passing. The race track includes a pavement that defines a turn, a first path around the turn, and a second path around the turn. The second path is longer than the first path, and the two paths are spaced-apart such that a first car can travel on the first path and a second car can travel on the second path in an overlapped position relative to the first car. At least a portion of the first path passing over a plurality of depressions defined in the pavement at predetermined positions. The depressions configured to reduce the amount of friction available to the first car such that the first car is slowed sufficiently for the second car to maintain the overlap position or pass the first car through the turn as the second car travels on the longer second path.
