If your vehicle doesn't make noise, people won't hear you. It's true. I've been weedeating the curb before and had an electric vehicle pass me. It was just a silent flash of vehicle. It's creepy enough to startle you if they surprise you. This is why bikers always have annoyingly loud pipes. Loud pipes do, in fact, save lives. That is a problem for Domino's new silent electric delivery scooters...

So what was their answer? They recorded hilarious scooter sounds, put a speaker system on each scooter to project it, and the world is a funnier place for it.
