"Warning noises are only useful if they they aren't routine sounds. If that sound is emitted continously all around you, you do tend to filter it out."
If you are in a lorry nest, yes, you would hear those annoying backup beeps too much. If you are walking or cycling down the street without earbuds blasting loud enough to leave only 30 minutes of battery time at a go, you might detect a car backing out of a drive where there is limited sight lines.
I don't just randomly swerve into the lane while riding my bike so I'm not that worried about EV's making an artificial noise when they are going forward. I sort of think it a good way to weed out the idiots even at the cost of a few surviving.
