The original program was conducted with tape measures, stop watches, and cones. For example, to deter- mine stopping distance, drivers would brake at the set cone and the distance to full stop was measured. Wanting to be a bit more scientific, the team later mounted a fifth wheel on the vehicle capable of measuring distance as well as speed. The braking and acceleration evaluations have been—and are still today—conducted at the Chrysler Proving Grounds. The dynamic road course, on the other hand, moved around a bit. The course started by utilizing the road course just outside the Michigan International Speedway. Due to deterioration and decreasing road conditions, the testing vehicle dynamics were moved to Grattan. The speedway's site reports that the last time the exterior road course was "officially" used was 1973. One of the iconic images of law enforcement vehicles includes just two wheels, yet motorcycles weren't introduced into the testing program until September 2006, for the 2007 model years. More recent years moved the motorcycle course from the MSP training grounds to the same Grattan Raceway.

"We [then] went to a company called Datron. They used a non-contact optical sensor," says McCarthy. It recorded the vehicle's speed and distance by detecting the ground as it moved past the lens. "It became much more accurate than click- ing the stop watch as fast as you can." With a new year came another mea- suring equipment change, and MSP looked to the skies for help. "Now we're actually using GPS-based equipment to Michigan State Police's 1975 Plymouth Grand Fur y. With a 400 cubic inch engine, its claimed to be the last full size patrol vehicle with an "R" style body.
