Beyond the traditional purposes of moving people, goods, raw materials, and mail from place to place lies a world of unconventional uses of motor vehicles. Rolling grocery stores, churches, classrooms and health clinics have taken traditionally stationary services directly to those who need them. Companies have built vehicles in the shapes of their products (the Oscar Mayer Wienermobile being just one famous example) from the early years of automobiles. This lively history gives a fascinating overview of the many special purposes vehicles have served. The unconventional uses of motor vehicles stretch one's imagination. The author here divides them into eight types based on their purposes and uses. Sales vehicles support a successful sales volume; advertising vehicles retain present customers and attract new ones; education and training vehicles provide skills updates for employees; charity vehicles are used to serve various populations of the needy, suffering, and distressed; religious vehicles promote a particular faith; functional vehicles perform an on-the-spot function normally done by a fixed-base facility; multimodal vehicles have the ability to traverse land, water, and air; and government vehicles provide a host of services to constituencies. Examples are provided for each type of vehicle and examples from other nations besides the United States are included as well.
