Fabulous idea. There has to be an easy way to add a system to the car that would give audible warnings to others. It should be louder than traffic. Also it should be easily accessible by the driver. Perhaps a button or even padded area on the steering wheel that the driver could easily reach. Then by some magical means, or by electricity, or maybe engine vacuum when the button that gets pushed goes to a device that makes sound to alert pedestrians of the approaching car.
It seems like a lot of complicated stuff, but I’m sure it could be worked out. We could name it after a wind instrument, like a flute, or clarinet, or…
hmmm… then there also should be an industrial standard for this button so it can be understood in all languages. Please bare with me, but I think this may catch on as a symbol that would produce an audible warning.
