Electric cars and mobility scooters are very quiet,I find it difficult to hear them sneaking around.
By attaching Hot Rodder engine battery operated toy bike engines to these electric vehicles I may now hear their approach and jump to one side.

[+] but long ago I decided on <link> for my electric car sound. |
|

You would be far, far from the first person to suggest electric cars that make engine noises. Personally I think if you're going to have a louder electric car, you should give it a unique electric noise, like the Tesla Roadster. |

Pennies in the hubcaps. Actually this is an opportunity for some
enterprising grad student eith a 3d printer to print out an infinity of
variations of "penny" and "hubcap" shapes to see what cobination
produce the most/ most-interesting sounds. |
|
| |
So...electric vehicle noisemakers? Baked, although [+] for the way you suggest producing the noise. |
|
| |
In the USA, there's actually been talk (and at least one proposed law) regarding making noisemakers mandatory in electric cars for safety reasons. |

Mobility scooters...the thought of a loud vroom coming from one of those would be hilarious. Same goes golf carts... |
