Like I mentioned before, this one's irrelevant since I've always turned my lights on when it's raining. I was running errands yesterday around 2:30pm when it was pouring and I figure at least a third of the drivers around didn't have their lights on.

Of course, being the cynic that I am, I assume that of those who did have their lights on, many didn't actually turn them on themselves, but rather it was just dark enough for their autoheadlights to engage. Hehe.
