I don't mind these products, in fact I think adding some sound back to the EVs would do well for folks (like myself) who really miss the pomp and circumstance that came from an I6, V8/10/12.
That said, I wouldn't want my EV to sound....like an ICE. If I want a V8, I'll buy a M5 or an E63. Because fake shifting noises on an EV are just kinda....lame.
For an EV, I'd want some cool space-y type sounds like the Taycan offers, and that make more sense with an EV. And I dont think that exists with any of these systems.
