Maybe lower than you think... several Ford products over the last few years have done things like run sound tubes to the cabin or use the radio to simulate engine noise. I think it's kind of silly myself, but whatever.

Or at least people with different interests. Just because you think your own interests make sense doesn't mean other people have to agree or share the same interests that you do.
> Every F‑TYPE is fitted with an Active Sports Exhaust that creates a race‑car inspired crescendo.
> The exhaust system reacts to throttle position, speed and engine revs by opening active valves. When open, these valves allow exhaust gases to take a more direct, less restrictive route through the rear silencer producing a much richer, more exhilarating sound. Where fitted, the Switchable Active Exhaust, allows you to manually open the exhaust valves so you can enjoy F‑TYPE’s stirring soundtrack at all engine speeds. This feature is optional on F‑TYPE and standard on all other models.
Legality of use on public roads varies...
