What is a wolf pack on an expressway?

Excuse me, could you please clarify what you mean by "wolf pack on an expressway"? Is this a reference to a group of actual wolves somehow present on a highway, or is it a colloquial term for something else entirely? I'm not familiar with this specific phrase in the context of finance or cryptocurrency, so I'm curious to know if it's a metaphor or a literal description. If it's a metaphor, could you elaborate on how it's used and what it signifies in the world of finance or cryptocurrency?
