It is, after all, the best side of the road. But how did it become the crowd favorite of most drivers on the planet?

In the latest installment of MinuteEarth, Henry Reich (creator of the similarly named MinutePhysics) takes a break from his typical mathematical antics to dig into some history. Specifically, he’s looking at why roughly one-in-three earthlings drives on the left side of the road, and why the rest of us Normals prefer to do so on the right – i.e. the dextral (and also the correct, just and honorable) – side of the road.
