A Chicago-area Audi dealer has pulled off the rare hat trick of combining a manufacturer ad, a public-service announcement, and some serious ego gratification for an R8 GT customer by putting up this billboard.

Here's how achtung697 explains this image over on Reddit.

My friend's dad got himself the new Audi R8 GT. The dealership he bought it from decided to make this billboard ad. They are doing it right!

Audi has played games with cheeky billboards before, but this may mark a new high in public customer appreciation. A quick reminder about proper lane discipline is never a bad thing, either.

If you're in the area, here's a picture of the Audi R8 GT with the billboard. You've been warned.
