It is clever, but from an advertising standpoint, it’s too busy.
It contains multiple messages, which is good, but it takes time to absorb all that.

A speeding motorist would not have time to take it all in. Maybe it is posted at an intersection where people have more than 1-2 seconds to soak it all in.

Too cluttered for passing motorists, but now that it’s gone national, it can go viral to computer screens everwhere.

Yep. I knew the art critics would show up, sooner or later! ;)

I'm betting there are a lot of folks there who are whipping a U-turn and going back for another look.

Think again.

How many other billboards reach a billion Freepers, plus whatever other "national" outlets have picked it up?

Sounds like good advertising to me...
