When the first hybrids hit the streets, just about everyone was shocked at how quiet their engines were. This has only increased with completely electric cars. While some people love how quiet these vehicles are, other people miss the powerful sound of the engine. Governments and civilians alike have brought up the fact that these cars can be safety hazards, especially for pedestrians and especially for the visually impaired. Soon these concerns will be a thing of the past. Not only are regulators requiring that electric vehicles come equipped with sounds, owners of these vehicles will soon be able to choose their own bells and whistles. In the United Kingdom, car producers will provide several sound options to the owners of electric vehicles according to the National Highway Traffic Safety Administration (NHTSA). The laws in some countries will demand that cars generate some kind of a noise when they are going slower than 19 mph while others have different standards.
