> Sound waves are captured from electro-mechanical vibration in the axles that are equalised, amplified and delivered alongside visual feedback to inform the driver

In other words, they made an EV do wroom-wroom?

I can’t decide if that’s dumber than generating a fake sound or not. Kinda think it is, just because it’s more things to break and needing fixing. Also “a cricket crawled in there so now my half a million dollar Ferrari sounds like a cricket” would be a funny possibility I think.

Isn’t this quite literally how a microphone works?

I love Ferraris trying to sound like Yutong buses.

Yes, but it still seems like a cool choice worth talking about. They could have made a totally fake engine noise, instead they mic’d up the axles.

Or, like, keep it silent as it is? Imagine iPhone converting signals an data lines to sound to imitate dial-up modem noises

most jurisdictions mandate some minimum noise level for pedestrian safety, and cars have to implement artificial noise at low speeds to meet that requirement. (above a fairly slow speed, the tire noise is more than loud enough)

That's a reasonable requirement, but it clearly says the noise is for the driver, not pedestrians

The Mustang Mach-E makes a fake engine sound: https://www.drive.com.au/news/ford-mustang-mach-e-v8-exhaust...

I don't understand why electric cars cannot simply stay silent, except maybe some pedestrian warning ambient noise. Are the operating noises of the electric car somehow repulsive?
