From Jaguar's website:
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.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.
> cars are designed for stupid wankers
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.

Legality of use on public roads varies...
It's a significant problem here in London: Supercars (and regular cars and motorbikes that have been modified to have noisy exhausts) make up a tiny minority of vehicles on the road, but it only takes one to produce incredible noise levels that carry for many blocks and penetrate almost any soundproofing/double glazing.
It's completely unfair to subject so many people in such a dense city to these noises just for the thrills of one driver/rider. Stick to the track if you must drive such a noisy vehicle!
Politicians probably think of it as an annoyance to be shrugged off, but it does genuine economic harm. It damages property values near busy roads, and it makes our public spaces and parks unpleasant. Even in the middle of huge green areas like Hyde Park, you can still hear them roaring down park lane etc.
