Some EVs have mandatory sound emitters to not be fully silent (and thus dangerous). I thought it was weird harmonics from the synRM engine but it's synthetic and enforced by regulations.

Hybrids as well. The Toyota Prius has had this at low velocities since before EV cars were mass produced (I believe Toyota uses a speaker that makes a sort of sci fi sound). It is a legal requirement to generate a minimum amount of noise to sell a car in some countries.
