Some champions built real life Mario Kart and it's the best thing you'll see today

The first half of the following video details how, exactly, the "cowboy engineers" at Waterloo Labs built the famous item system of Mario Kart into an actual go-kart track. It took some servomotors, remotely-controlled steering columns, and an RFID system so that the karts could communicate with one another (and also, evidently, some cardboard boxes and masking tape and elbow grease to make the item boxes).

The second half of the video is merely bliss incarnate. Please enjoy.
