I wrote one script that could be classified as a road picture but it was probably way too esoteric for its own good. Two quarreling brothers off to find their dad who had disappeared into the bayou country, having joined a violent anti-government militia movement. It kinda' played, ultimately, like O Brother Where Art Thou, but not nearly as clever or cool.
It was, however, to answer your question Scott, fun and easy to write.
Let's face it, you put two characters in a car and ladle on the conflict, the thing is mostly going to write itself.
My old collaborator was a "road movie" junkie and every third script he proposed was out on the open highways. Kinda' made me nuts at the time.
For me, the best road films happen to also have the word "road" in the title... give me Bob and Bing any day!
