Too Quiet

A couple years ago, folks were worried that those electric cars might be too quiet. Anyone who's ever been to South Tucson knows the answer to that problem: turn up the stereo!

If it was up to me, I'd put a separate stereo in them, an inside set for the enjoyment of the driver, and an outside set with all-weather speakers to warn pedestrians. They'd play the customer's choice of constant audio... I can already imagine what that could be:

• Harley-Davidson RumbleTM
• Kenworth diesel idling
• Playing card in the bicycle spokes
• Ferrari revving
• Little kid making "Vrrrroom, vroom!" noises

What would you play?
