the upgrade I really want, innovation or mindless dribble?

Re: the upgrade I really want, innovation or mindless dribble?

Exactly, that's one of the many uses I envisioned.
The other one being obviously to play "ARTILLERY, YOUR AREA"/barrage sounds to them to see if they GTFO in panic. Or generally cause mischief by making enemy team/really loud bird sounds when they've heard you moving, so they don't keep searching.
Also getting your teammates out of the way. Many people misinterpret the honking of the car horn quite a lot - and indeed it isn't clear what is meant (get out of the way? get in?) at all times. Being able to shout "GANGWAY! HOT STUFF COMIN' THROUGH!" as you race around in wild abandon would also cause a decline in vehicle TKs.
Of course, I would also use it for plain absurdity (hiding in trees, playing TRAIN_BRAKE_SKREETCH.WAV to them at extra high volume).

roflmao! Thats classic! I'd love that.

Psychological tactics in games is always fun. Make the enemy think you are were you aren't.

Also it would be fun to make them die from me driving around in my APC belting out the Spice Girls. Enough to make any man die from pain in the ears.
