The work chronicles the mechanical and commercial evolution of the horseless vehicle, tracing early experiments in France, England, Germany and the United States and the gradual emergence of a practical automobile. It examines commercialization, mass production and parts standardization, highlighting the role of large-scale manufacturing in lowering prices and expanding ownership, and treats the industry's economic consequences, investment opportunities, and social benefits. The author emphasizes how cooperation among manufacturers and production for mass markets generated substantial profits, and an appended chapter provides an editor's account of contemporary industrial conditions and figures.
