Mirror driver

Using your rearview mirror while driving to observe drivers behind you in order to play mind games while anticipating their moves to inconvenience and/or irritate them. ie: when a vehicle is coming up from behind, the mirror driver will slow down in a place where the tailing vehicle cannot pass so they must slow down and remain behind them. As soon as the tailing car is able to pass the mirror driver, they speed up again. Mirror drivers do this because it gives them a power trip.

I can tell this guy is a mirror driver as I am approaching him.
