This is probably generally true, but on at least twice I have blown people away to the point of having to comment:
Both happened in what I call the “Baby Chuck Truck” (BCT) and both incidents happened in the mid to late 80’s.
I wish I had a picture of the BCT, but you will have to make do with a description.
The BCT was a powder blue 1971 Chevey C10. The side panels had rusted off and were replaced with plywood, though the tailgate was still steel. It had an old Radio Shack AM/FM 8-track in it and sounded like King Kong with indigestion while running. This required unusual volume levels while moving. In addition, whoever added the AM/FM 8-Track had connected it in such a way that it ran, whether the truck was on or not. It had some rust issues, and on the front fenders was scrawled in goober-like printing with white paint were the words: Chuck “Baby” Bill.
I was given this truck by my father who got it from who-knows-where while newly married and going back to school (we had also just had our first baby).
So, I’m sitting at a stop light in Shively (hic central) in the BCT listening to “Rhapsody in Blue” with full orchestra cranked to hear it over the roaring engine.
Car next to me: What are you listening to?
Me: Rhapsody in Blue
CNTM: Okay, never heard that before.
The second incident happened while refueling the BCT in Indiana. Brahms Violin Concerto was playing and I didn’t feel like not listening while parked. So, I let it run while refueling (didn’t have to leave the truck on to do this–I love that feature).
Guy at next pump: I never, in a million years would have expected to hear that coming from that vehicle.
Me: You choose what’s important.
GANP: Guess so.
Now, of course, I’m currently in a position to pick my vehicles, and really wish somebody would get a good Hybrid truck going, because, I like trucks, but can’t currently afford the kind of gas, and wouldn’t want to spend that kind of gas, on my daily commute.
Moral: Generalizations can be problimatic, even if they are mostly correct.
