Why might a motorcycle moving around in their lane?

They’re actively looking for your face in the mirror, so they can tell you can see them. The other reason is lane protection, especially in merging situations. If I’m riding in the right-hand lane but know traffic is diving into this lane so they can exit, I will sit in the left side of the lane. Jul 19, 2016
