Auto Absolution

I don't know what a lumbar is or why it needs support. (Like most guys, I also do not know what a duvet is -- or why it needs a cover.) I bring this up because I discovered a button on my car that says Lumbar Support. When pressed, it makes the driver's seat very uncomfortable. Maybe it's like penance. If you're bad, you press the button and all your sins go away as a reward for driving around in great discomfort, the mechanical equivalent of a hairshirt. Maybe not.
