Track days. They are a simple test between human and machine.
The subject of track days came about during a discussion on advanced driver education programs. There has been a push to create driver education programs for teenagers by teaching them advanced, but necessary skills. Car control is a huge piece of the puzzle, as teenagers need to understand how their vehicle can react when presented with a dangerous situation. It used to be called "defensive driving," but teaching these skills on controlled environments raises this concept to new levels.
