One reason I like the "chirp" noise on the Volt. A tiny "bip" on a car horn is either not heard, ignored, or taken as offensively as if you were laying on the horn continually, even if the pedestrian you're bipping is doing something stupid like walking down the middle of a lane. The Volt's chirp is unusual enough a sound that it cuts through all the other surrounding noise and is not met with as much offense.
