Heh... i couldn't imagine driving my friends WRX on city streets. The noise is insanely loud and on the track i could always tell exactly where he was even a mile away on the far end.

The weekend we spent at Spring Mountain, the only car louder was a bright blue GT3 with a huge wing.

 

It would be an excellent anti car jacking feature as well. Just bounce it off the limiter a couple of times and launch. Watch criminal burn up in rearview. Laugh all the way home.
