DXDT means velocity, whether defined as "delta x divided by delta t, change in position relative to change in time," or, simply "math" for "velocity." DXDT means speed. To be the fastest driver, a simple concept, yet devilishly difficult to achieve, velocity is the ultimate measure of performance. The fastest car is most often the one that wins.
