Car mats! What’s unfamiliar to people today? Right: the HUMP. I’d forgotten all about the hump. You couldn’t balance anything on the hump, like a drink; it would fall off. You couldn’t sit on the hump because there wasn’t any place for your knees, but sometimes if the car was crowded you got the backseat hump anyway.

Then came the day when your car had no hump, and then none of your friends' cars had humps, and then everyone forgot about the hump.
