Have you ever wondered "Where the hell is the culprit for the traffic jam??!?"

I believed everyone's been through it, stucked in a traffic jam, trying to push your torsos a few inches higher trying to see just what the hell happened up front. Wild guesses ranged anything from accidents, road blocks, mass migration of frogs or crabs etc. Then you got to a point where you suddenly realize you're traveling 80km/h and there's no jam at all, as if everyone just decides to all go slowly and then fast. Watch this video as Japanese researchers put together a few dozen cars on a circular 'road' with a 200 meter diameter, spaced evenly apart and asked them to drive at the same speed, guessed what? Before long, traffic jam occurred, and spread like a shockwave through the circle, and it never ends from then on. Imagine how much petrol and time was wasted through this annually.
