Heh. I wanna be the first to market to "custom movement-tones" for Priuses (Priusi?) Downloadable and complete with scubscription scams. I'll be rich! I wonder if the car sound from The Jetsons has fallen out of copyright?
Um. Patent pending on automatically changing arbitrary sounds in ways that indicate velocity! Yeah. Right.
Sounds like really good marketing spin for me...Prius, a car so quiet and smooth you won't even realise its moving unless you deliberately make it noisy.
I think Toyota need all the good publicity they can get at the moment!
The Prius does come with a horn does it not? To me that signifies all you need to make pedestrians "get out of the way".
However if they changed the sound to something like an Abrams tank then I think that would be more effective than a horn.
Or simply re-market the Prius as a "criminals car", you know some thing like.."Prius, so quiet the only thing you need to
worry about is your stolen schwag making noise !" Or perhaps market it for the military..."Prius, so quiet your enemy
will never know what hit them !" Still I think I would prefer a Terminator version only because I think thats funny.
