Some wily vandal in Portland, Oregon has painted Mario Kart symbols into the pavement there on one of the city's bike lanes. You can see them in action in this video (also embedded after the break). Unfortunately, the bananas, star and speed arrows don't actually confer the same powers they do in the game, but we did smirk to see that all of the bikers do faithfully avoid the banana peel, and hit the rest of the symbols head on.
You can even wring some unintentional hilarity from the dry-as-a-Dry Bones explanation of what each powerup does by the KATU anchor. That's right, Carl Click! You might have read that script just fine, but admit it: You don't know a Red Shell from a Blooper.
