Two old friends bump into each other at the gas station one day. While they're filling their tanks and inhaling their fair share of gas fumes, one of them says to the other, "Boy, I really do miss them. You know, my old car had two of them, and I'm sure yours did, too. But you can't get them now on any new car, even a Cadillac or a Rolls Royce."
The friend shakes his head in agreement. "Yeah, too bad. I'm sure some pickup trucks and SUVs still have them, but you won't find them on a passenger car anymore, anywhere, anyhow."
What were they talking about?
