It’s not even an electric car thing - my Focus ST came from the factory with a little sound pipe thingy from the engine to the cabin to make it feel more racy. When I bought it used it was disconnected, which is fine, because the MBRP 2.5” cat back exhaust already installed is about 3x louder than stock.
I’m pretty sure BMW was doing it too when they started going all turbo and losing the song of the NA.
I drove a BMW x5 a couple of years back, and it piped fake engine noise into the cabin. IIRC, it was a petrol v6/v8, so was quite capable of making it's own sound, so the whole thing was pointless - but worse, the fake engine noise sounded totally fake! Honestly, I felt pretty silly with it enabled!
There a lot of things that make a car feel faster, and giving them higher displacement engines and louder exhausts has more disadvantages than it’s worth for most people.
You can get the same experience with slightly more cabin noise (that doesn’t annoy your neighbours), a longer first gear, kickdown pedal, etc.
It’s kinda like Coke Zero. If you can get 95% of the same experience, why opt for the sugar?
