I think a good artificial noise for electric cars to generate, so they are audible enough for pedestrians and others to be aware of them nearby, would be the synths from Darude's Sandstorm.
@jackdaw_ruiz I wonder if rather than making electric cars noisier we should have regulations on vehicles that are too noisy?
@Workshopshed @jackdaw_ruiz We most definitely should, since noise pollution is no small issue, affecting the collective environment and individual health: https://electrek.co/2023/03/20/we-require-noisy-evs-for-safety-but-lets-stop-the-real-killers-suvs-gas/
We require noisy EVs for safety, but let’s stop the real killers: SUVs & gas

Noisy, gas-guzzling trucks & SUVs kill pedestrians (and everyone else) at vastly higher rates than EVs. Why do they get a free pass?
