Nothing to me has more excitement than the experience of rising early in the morning in my own house and getting into my car and driving away on a long, meandering trip through North America. Not much can beat it for a sense of freedom—no pat-down, no passport, no airport muddle, just revving an engine and then “Eat my dust.” The long, improvisational road trip by car is quintessentially American, beginning with reliable autos, early in the last century.
