My initial thought was: I wouldn't want any 'fake' noise, potentially hiding information in the (softer) real noise. But what if the noise is dynamically synthesized based on lots of info from the vehicle – perhaps not just its real noise/RPMs, but other qualities usually not usually sensed. Temperature and vibrations across multiple sampling-locations? Computed fuel-economy? Others? Maybe it's a good aural channel for real info!
