If I had an understanding of engineering and several friends with the same passion for video games and being a nerd as I do, then this would have happened in my life.
For now I will look upon these guys in envy for being bored and creative enough to make Mario Kart REAL!
They have Stars and Mushrooms and everything! The cool thing is that the items actually work on the opposing persons cart!
When the sensors on the cart read that you are holding a star, the throttle becomes free and you can touch others with the star and turn their carts off! It's insane how far these guys went to make this a reality.
Totally worth it...
