Ha! Then here’s a paradox: The force that enables you to move—let’s say to walk—is static friction, not kinetic friction. When you push off the ground with your back foot, static friction keeps your foot from sliding out from under you. (For laughs, see my recent article about trying to climb out of an ice bowl.) The same is true for the locomotive: It uses static friction to drive itself forward.

But what if we could have overlapping implementations? It would simplify the trait implementation for a lot of types. For example, we might want to automatically implement Serialize for any type that contains a byte slice, or for any type that implements IntoIterator, or even for any type that implements Display. The real challenge isn't in how we implement them, but rather in how we choose from these multiple, generic implementations.
