On the other hand, one doesn't need to actually send music or speech to send useful information. The traditional speed grooves are essentially a single-bit, "wake up!" signal. One could imagine using descending pitches to signal "slow down!", or a trill to indicate "curves ahead". For that matter, one could use short bursts of Morse code to signal "tune radio to traffic information" or similar.
