I've seen this on a couple of other forums (fora?) and it seemed like that was the biggest surprise for most people (including me). I can't imagine driving in that position, especially at those speeds for that length of time.
I have read all the books. That's why I was asking. I didn't remember that scene and it seemed out of order to me. But I went back and re-read a couple of wiki posts and it looks like it happens. I hadn't thought of it as happening on that scale, however.
