The "flashers in the rain" problem became so problematic that a few years ago, the Florida Legislature amended our traffic laws and outlawed flashers in the rain.
We even had notices on the electronic info boards saying "Headlights ON, Hazards OFF -- It's the LAW!"
And the morons among us revolted! They raised such a fuss that last year, the Legislature repealed the prohibition against flashers. And that is a sad, but true, story.
