I badly want this in my 228i.
As a matter of fact - I thought I invented this but clearly, BMW beat me to market
I was planning to run my internal ASD line feed through an amp to a weatherproof speaker under the car next to the stock muffler.
That's basically what this system does, in a nice single package, and if course with its own ASD module with sounds appropriate for the outside. I bet it's going to crackle and pop like crazy. Think about the hacking possibilities, a gurgling muscle V8 or a lambo V12.
Sorry guys hate the idea as much as you want but this is the future, I wouldn't be surprised to see something like this on electric cars soon. Very much like the turn signal clicking you hear in your car is not a relay clicking anymore...it's just a sound effect. It could beep or sing but people still insist on the click...
