FWIW I haven't heard the word "hot rod" in a long time, so that could be some indicator.

It's not to say that "nice cars" are disappearing though. When I was a literal child in rural Appalachia, the standard fare Dream Car was a Dodge Viper or a Corvette and I did indeed admire those cars. But tastes certainly change as you get older and while I still have a "nice car", it's of a different breed than the All-American Dream Car.

I'd dare say that demographic died off and hasn't been replaced due to cultural and economic shifts. Also, the whirl of a turbo is a more appealing sound than the roar of a supercharged V8, to me anyways.

Edit: and yeah those types of guys just drive a lifted diesel truck with giant wheels now. At least they can do work with them.
