I’m team wheels all the way. Almost all doors rely on a swinging hinge system. These hinges are sheets of metal, the part that is then bolted to the door, that spin around a central axle. This mechanism, even though it doesn’t ever complete a full rotation, is still classified as a wheel. (It’s all just simple machine science.) A door is made of multiple wheels, so how can people still argue that there are more doors in the world?
