Rear View Tourism 

The act of deliberately using your rear view mirror to look into the car behind to check out what the driver/occupants are doing.

"Hey man, on the way in this morning, there's this woman punching out her husband in the car behind me. I even started yelling her on."

"You've got to give up this rear view tourism, pal."
