I drive a car to get places, and some nice music or an audio book is a nice way to pass the time sitting in stop and go traffic on the way to or from work or coasting down the highway with the cruise on.
As far as the article in the first post goes, surface-mount exciters have been around for a while, though I've never heard of them being integrated into a car audio system. Sony has adopted a similar tech with for the audio systems in their OLED TVs, and supposedly those sound very nice for TV speakers, so there could be something to it.
Still, I'm skeptical about how good these systems could sound until I get a chance to hear one myself.
