Mormon Block

Two cars driving side-by-side at the same slow speed on a highway, thus blocking others from passing. This slang imagines a family with many children forced to take two cars and then drive in a manner that is oblivious to other traffic and others around them.

Those two cars are doing the Mormon Block and slowing the entire highway down to 40.
