Another modern car gripe: reverse warning sounds

I'm going to be very blunt here because I've just been woken up by this yet again: who's fucking stupid idea are reversing warning sounds on cars?

I do not need to be woken up at 11.45PM or 1AM or 3AM because one of my neighbours has been somewhere or come back from somewhere and needs to reverse their car. I do not need to here BONG BONG BONG BONG BONG late at night or in the early hours of the morning. There are at least two cars in our cul-de-sac with this feature as far as I can tell and it's absolutely fucking maddening.

Which fuckwitted numbskull moron thought this was a good idea? How many people are actually hit and/or injured by reversing cars globally on an annual basis? Very few I'd wager. Bu... bu... bu... meeerr... electric.... duurrrr... hybrid.... murrrr.... quiet. I. DON'T. CARE. SHUT. UP. WITH. THE. STUPID. WARNING. SOUNDS.

Seriously, why is this becoming a thing and why aren't more people up in arms about it? Can they be permanently disabled and people who own these cars just don't know it's a setting they can change, or are they mandated to be always on?
