Obviously you haven't put many miles on. It's not if you go in the ditch, it's when. You can talk like you're the best driver in the world, but sometimes it's unavoidable. This coming from a guy who has never had an at fault accident and used to drive professionally (still do, just not as much as previously).
The only time I can understand it is if someone is trying to avoid an accident. But to be driving on a highway with no one around and just go in the ditch, somethings wrong.
