Quite a good analogy for 'pantsing'.
Excerpt from article ... http://tuesdayserial.com/?p=2032 ...
"As a young child, we’ll say 16 since that’s legal driving age and we don’t know each other very well, I would take the family station wagon and try to out drive my sadness. In the dark, I’d start down a dusty road and drive. The mountains ran East to West, so I knew I was going East. I knew if I drove a long, long way, I’d end up in Riverside or San Bernardino. I’d peer over the steering wheel, pop in a tape cassette and press the pedal. Great serial fiction is created in the same fashion. I could only see to the edges of the headlights. You have to have some idea of where you’re going, and enough gas to get there, but otherwise, the writer can only see to the edge of your headlights. This is how Dickens wrote. Sir Arthur Conan Doyle wrote Sherlock Holmes in this manner. Heck, it’s how J.J. Abrams creates his successful TV shows, Lost, Fringe and others. It’s just how it’s done."
