We live next to an interstate highway, and the front yard is pretty loud; you need to speak up to be heard. However, I used to say that in 20 years, we wouldn’t hear that highway because the internal combustion engine would be out of style.
Fortunately, the government is working to save the endangered Noise Pollution:
Electric and hybrid vehicles may be better for the environment, but the California Legislature says they’re bad for the blind.
It has passed a bill to ensure that the vehicles make enough noise to be heard by visually impaired people about to cross a street.
