"One day while driving east on I-290" begins this Penthouse Forum-esque footage of a Chicago couple unabashedly "smashing" in the driver's seat while cruising along the Eisenhower expressway.

Come for the proud parents-to-be happily humping away in flagrant disregard for the rules of road sex, stay for the classy commentary from the two eager beavers in the adjacent car desperately trying to secure the money shot.
