Utter Phonyness
I think the idea matches this other one: Having your house full of vases filled with artificial flowers and embalmed birds with crystal eyes perched on dead and varnished branches in the living room.
Silence is gold. Silence is luxury, like cut flowers. Specially nowadays.
Who would be as psychotic as to want to be drowned in motor noise??
I understand that motorcyclists belong in that category, but inside a car, I would think you want as much silence as possible, either to listen to your own thoughts, your traveling companion conversation, music or podcast voices --debates, theater, lectures, etc.-- but if somebody came out with artificial sound... maybe they know that there's always somebody out there to buy it.
