These "technologies" are unbelievably "cringe" (for a lack of a better word).

Car enthusiasts want the sound to come from some mechanical aspect. They want the sound and smell of burning fuel, pushing pistons up and down at extreme speeds with hundreds of other rotating and spinning parts working in unison for a cool sound.

A speaker diaphragm moving up and down 20 to 100 times a second doesn't quite scratch that itch. A speaker can nearly "replicate" any sound, which takes the fun out of it.
