When a driver applies his or her brakes for no other reason than they see someone else applying their brakes in another lane. The offender has no other reason to slow down other than they saw some red lights in their peripheral vision.
"This dude is making me late for work, he's put on the sympathy brake for every car that has slowed down around him."
