18: Sound Effects
We all know that celebrities love to be seen and heard. But in an electric vehicle, this can be difficult to achieve. So, many celebrities have added aftermarket sound effects to their high-end electric vehicles. While this might defeat the purpose of an electric vehicle, many find it appealing coupled with the performance you get from a car like the Tesla Model S.

It makes sense to have some type of sound to get noticed. The sound effects you can get for electric vehicles are pretty substantial. You’d be hard-pressed to find a better-sounding electric vehicle, which is why many flocks to these types of add-ons in the celebrity world.
