In 1939, nine Westacres residents bought a used bus to share the cost of commuting to work at the Chrysler plant in Highland Park. They formed the Westacres Chrysler Employee Transportation Association, which grew to 25 workers who paid dues for the purchase and operation of a series of buses over the years. They issued stock, elected officials, and shared maintenance and driving duties. Over 50 years, the program gained national attention as America's longest-running privately funded ride share program. Gas rationing during World War II motivated the men to continue their cost-effective solution.
