The D1GP drift series has been prototyping and fine-tuning an electronic judging system based on custom sensors that record and transmit car data to a computer that judges the run. This system is also being tested in some European series. It is designed to remove subjectivity and/or predisposition of judges. Usually the track for such a system is broken up into several sections (usually three) and the system automatically generates scores based on speed, angle and fluidity of the driver in each section, combining the scores for the final score. In certain situations judges can change or overrule a score, which happens, though rarely.
