Trust me, you will totally dig this video of something that seems so so simple. However, the Rotogrip Automatic Chain Traction Device is fun to watch in action and, I assume, a great invention that will make driving in any condition much easier and quicker. The Rotogrip Automatic Snow Chains and Ice Chains work via a rotor mechanism that spins a fan of short chains beneath the tires as the vehicle drives. Though they’d work on any car, truck, or van, they were designed to work on buses and commercial trucks. They increase traction on snow and ice by 45%.
That is sooo crazy. More crazyness in the next video below!
