There have been a number of suggestions that electric cars are too quiet for pedestrians to hear.
Well, here's a car that warns pedestrians it's coming with the sound of horses hooves. Now that's original.
Can you imagine the reaction of someone who's had a few too many to drink and hears this?
How would like this in your neighborhood late at night on a warm summer's evening when you've all your windows open and are just drifting off into a good night's slumber? I hope the horn doesn't have a neighing sound.
