美国以其主要公路网而闻名，这些公路网旨在帮助司机在尽可能短的时间内从一个地方到达另一个地方。这些宽阔的现代化道路一般都维护得很好，很少有急弯和直道，但直路并不总是最好的。大型高速公路经常经过风景区和有趣的小镇。此外，这些高速公路通常位于大城市中心，这意味着在高峰时间它们会被拥挤的交通堵塞，“快速、直接”的路线变成了非常慢的路线。然而，如果你不着急的话，几乎总有另一条路可以到达。不是因为相对较新的“超级高速公路”,通常有穿过乡村的旧的、交通繁忙的道路。__11__都是好车道的路；其他的是崎岖不平的道路，蜿蜒穿过这个国家。这些次要路线可能沿着陡峭的山坡，沿着多山的悬崖，或者沿着令人恐惧的山坡，到达深谷中的城镇。虽然这些路线少，长，慢，但它们通常去的地方空气清新，风景优美，司机可能有机会获得一个清新，干净的世界视野。
