> Manufacturers are free to implement as much noise as they like. No. They are not. Nor have they been since at least the 1990s (probably longer) There are standards for "drive-by noise" as measured at various speeds, distances and throttle positions and these standards have been in places and constantly been revised (to be more comprehensive) over time. I'm unfamiliar with the specific FMVSS #s but I am familiar with the engineering shenanigans that have been implemented to meet them.
