What do you do about people blocking the passing lane?

Speaking of which, providing you are actually located in Minnesota, here is what your state says on the subject:

The law says that under normal driving circumstances you stay in the right lane unless passing.
Period.

This is not enforced. It would actually be impossible to enforce since traffic on the freeways would stop dead if it was.
