A billboard so ironic it could literally kill you.
This has to be the most counterproductive public service announcement since the "Ask That HR Lady With the Hot Tits About Sexual Harassment" campaign. At least maybe someone will actually do this, go careening into the base of the billboard, and send this whole dangerous distraction crashing to the ground. Yes, it would be a tragedy, but if you want to make a safer highway, you have to break a few idiots.
