"Just keep doing what you're doing, and you'll eventually drive your rental car directly into the sea"

This works as a rhetorical device, but if one were to try to accurately weigh two options against each other, it might pay not to use reductio ad absurdium and have something like "Continue on in the wrong direction until the ETA were passed or events made the incorrect direction obvious, then try a new route, having lost up to ETA." Which is still bad, but if no safe/available places to stop for directions presented themselves, might not be the worst option. But of course, by using the skill in the article, it would be a considered risk, and not an unexpected occurance.

Anyway, useful and easy to follow piece and I look forward to the next.
