What Features Do You Never Use?

I've always been fascinated by how long I can own a car and not use a specific feature, or touch a certain button. In some cases I've owned a car for years and literally never touched some buttons or levers (except for occasional cleaning).

What's in your car that you've never used?

I'll start. I've only owned my car for 6 months, but so far I've never used:

• Headlight switch. It was in "Auto" when I picked up the car and haven't touched it since.
• Windshield wiper stalk.
• Cruise control stalk.
