:offtopic:...maybe?

I was a at Suzuki dealer a couple of days ago getting oil and filter and they were closing shop and moving the bikes in. As I was leaving a sales person moved an electic bike in from the display corso out front and what an amazing thing 'not to see'. It moved so quick it was a blur over a 50 yard dash to the inside of the store - such a blur that I could tell it was a bike, could not tell what brand and vaguely got the color of the jacket the guy was wearing. It was silent and deadly fast.

So whats the answer for these things as far as louder exhausts go?; as they cannot be heard by others on the road or pedestrians crossing it. Perhaps a CD recording of a loud engine playing from an amplifier mounted on front and flashing lights perhaps as a backup 'cause you cant hear them.:confused1:
