The fact that electric and hybrid cars often have fake engine noises to help avoid collisions with pedestrians and cyclists is well known, but did you know that more mainstream cars augment and even replace their engine noise?

Some people aren’t too happy about it, thinking that the chicanery is all about fooling the consumer.
