Hybrid vehicles are a wonderful development, and it great that they are now routinely seen on roads throughout the world. But electric drive, especially at low speeds, is very quiet; far quieter than a typical internal combustion engine. And while that could be an appealing feature, in some respects it is more of a problem than a benefit.
In pedestrian environments, children, the vision-impaired, and others need the sound of vehicles to help locate them. President Obama has just signed the Pedestrian Safety Enhancement Act of 2010, which will eventually require that hybrids, electric vehicles, and other vehicles produce some sound to help keep surrounding pedestrians safe.
It's only the first step in the process. The law directs the Secretary of Transportation to "study and establish a motor vehicle safety standard that provides for a means of alerting blind and other pedestrians of motor vehicle operation." So it will be a few years before the requirement is established, and then a few years further, in all likelihood, for the effects of this to hit the streets.
