If you are trying to sneak up on your ex's house without being noticed you'll want to have the option of turning your lights off (make sure to use the emergency brake and not the normal brake pedal!). Also, if you want to annoy people, you can drive around with only your marker lamps at night by selecting the correct switch position. Also, the AUTO/OFF position can be rapidly switched to indicate to a fellow driver that their Prius does NOT have AUTOMATIC lights and they are driving 70mph down the highway in the middle of the night with their lights off.
