Much ado is made of noisy gas
Much ado is made of noisy gas engines, but most engines are rather quiet. At speed, it is road noise from wind and tires that dominates. In town, for observers, it is still tire noise that is the big noise generator The other day as I was walking in the neighborhood, the noisiest car to pass was a Tesla. The tires were much noisier than any other car that went by. The engines of gas cars were well muffled and didn't significantly contribute to the background noise. I have an electric car, and I like them. But for noise considerations, it's tires, tires, tires!
