re: Spinoff: How does one cop pull over multiple vehicles at a time?

While in college we were following some girls going to their apartment after the bar closed. Cop pulls up next to us and points to pull over then gets behind the girls and follows them to pull them over. We backed up on the shoulder of the 4 lane about a 1/4 mile to an exit we had just passed. Took exit and got lost as shite for about an hour in a Nation Wildlife Refuge on some dirt roads. Had a case of beer with us and didn't get a ticket or go to jail so it ended well.
