Around 1909, the city of Detroit began testing modern police cars, with hopes to supplement bicycle units, and mounted units.

Everyone knows this city as the heart of the American auto industry, with big names such as: Ford, Studebaker, Packard, and Cadillac. Croul saw that there was an ever-growning number of cars on the road, and city streets. This made him think about how useful they might have some use for the police of Detroit.

Their radio however, did have it's troubles like: working in tunnels, under bridges, and around tall buildings. Alsothe radio’s batteries, couldn’t fit in the car. To fix this issuse they installed it on the running boards of the Model T, it needed to be recharged every four hours, but
