Who doesn’t know the joys of Mario Kart. Just when you thought you lost the race, you get the iconic flying blue shell on your last lap, throwing the leader off of his race, and giving you one last chance at glory. It’s too bad shrinking lightning bolts, invincible stars, speed-ups and banana peels aren’t real life objects we can use during our daily commute. How awesome would that be? If you live in Portland, Oregon, you need not dream anymore, as you can get your Mario Kart on while using city bike lanes. Some anonymous joker has used clever stencils to re-create various power-ups and tokens on bike lanes. At the very least, it makes the daily commute a bit of a game. Just remember, if you hit other vehicles in this game, it might leave a mark.
