There's a side benefit to electric cars that are often cited as a minor but essential selling point. Electric and hybrid vehicles are the target of some new legislation. The legislation would require these quiet vehicles to make more noise. The technology is available to make cars noisier, but the government is considering mandating it.
How a quiet automobile can be dangerous
Hybrids and electric cars tend to be quite quiet when going slow. At speeds above 20 miles per hour, the air resistance against the vehicle does make some noise, but it is generally not as loud as gasoline-powered engines. Any person that needs vehicle noise won't like this, although it will help noise pollution. Those who need the sound consist of cyclist, the blind and pedestrians. They use the sound to determine how close or far away a vehicle is which is harder when the sound changed. Limited studies have shown that hybrids and electrics are twice as likely to collide with pedestrians at intersections and parking lots, where the vehicles are moving at very low speeds.
Those making vehicles concerned
The automobile sound issue is one that vehicle companies such as Nissan are working on. In the future, the Nissan Motors Leaf will make a noise. It was called a "futuristic buzzing noise" at one point. Kits to put into cars are being developed by Lotus Engineering and other companies. One kit makes a Prius sound like a race auto. Kits are also accessible to create 8- and 12-cylinder automobile sounds, so technology is already available to add sound to quiet hybrids and electric cars.
Creating a safer country
The National Highway Traffic Safety Administration is considering creating needs for electric vehicle noise. Regulation like this is being considered in the European Union. Automakers have been asking if it is possible to do natural noises. Most blind-advocacy groups are against this though. Worldwide criteria might be created by the Society of Automotive Engineers. It is hoping to keep the streets from having several random noises on them.
