The object of this challenge is to accelerate as fast as you can to some maximum speed and then apply maximum braking to slow to a stop as quickly as possible. Of course, you must stop in the box formed by the finish line and the line of cones. The length of the box, i.e. stopping zone, appears to be about 25 feet. The DeLorean is traveling about 80 mph when you begin braking. You thus have about one fourth of a second error window to catch the stopping zone. That is, there is an ideal point to put on the brakes. If you are an eighth of a second too early, you will stop short of the finish line. If you are one eighth of a second late, you will crash into the cones and be disqualified. In one sense, it seems incredible to me that one can estimate speed and distance on the screen of a computer with enough accuracy to achieve this goal, yet it is fairly easy for most people.
