I do wish someone would publish a study that linked distracted driving and auto deaths to roadside signage, such that more states would pass laws against it. Assuming there's a link, of course. I'm still not certain why state citizens across the country haven't risen up and had them banned more broadly; they benefit so few, and annoy so many. Without some concrete evidence of harm, does it come down to free speech fights in courts, where legislation is overturned? Or is there just so much apathy there's no public outcry?

I suppose most people, like myself, have just grown up accepting it as a fact of the landscape and think of it only occasionally in passing, and never take action against it.
