Many of the challenges to be met stem from America's surface transportation systems, and in particular the motor vehicle-highway system. Private investments in the automobile and public investments in highways have brought Americans unprecedented freedom of movement. Most individuals today have access to automobiles providing them with the means to pursue interests, jobs, recreation, and schooling in ways and places that would have been out of reach for most Americans just a few decades ago. Goods move quickly and efficiently on truck and intermodal truck-rail systems, supporting economic growth. Americans have incorporated the automobile and truck into nearly all aspects of life--the economy, society, and popular culture. |
