I mean the three:

-- the additional alarms you mention;

-- the noise from the engine (according to the assessment of mates, it should be that): it whines;

-- the additional noise made to increase their "presence" which is typically an unnatural synth chord.

All of that is absolutely unbearable to us.

There is literally any noise from the engine, whine or otherwise. Whether a noise is bad or not can be subjective but silence is objective.

So at least for that one it kind of draws into question your overall conclusions here. You might be hearing an ICE and thinking it is electric, or some specific badly tuned vehicle or something.

I am very certain I am talking about electrical and hybrid vehicles. The first one that had me aghast was a Nissan Leaf. Today, too many. Obviously I cannot confuse them with ICE ("brooom").

The point about the "whining possibly-engine" comes from a chat with a friend, where I said that they had decided to really use the most annoying overlapped noises to make the cars audible: he replied, those are not the additional noises, but the "noises from the engine" (probably from the whole system). I don't know.

> silence is objective

The electrical and hybrid vehicles I witnessed are very far from silent (save for the bicycles - I can't assess them, too little experience). As expressed, to us those noises - running noises and operational noises - are annoying to a whole new level.

Nissan Leaf motor is silent, there's really just objectively not a noise from the motor itself which could offend you.

There's still some possibilities here: maybe you came across someone with a broken car and believed that to be representative.

Most other explanations here just involve some form of confusion on your part to be honest: that it was the backup-alert noise that it makes _because_ the car is otherwise too silent, that it wasn't actually a Leaf but an ICE engine that you saw, or something else.

[mdp2021]

I insist. It cannot be about broken cars, because there would be a large number of them.

The Nissan Leaf cars I experienced are not silent at all - it does not matter if it is the motor or another part of the system, or if it is the additional noise that was mandated legally because they were deemed too silent. Similarly, its Peugeot "twin" is "whaaa" whining, and so are the hybrid Jeep Renegade, and many others (as I was writing another reply nearby a Lexus) that had me turn in the street and address the drivers with impatience.

Is it possible instead that you have no noise sensitivity for that noise? Or maybe - that makes no sense but - if I pointed you to that noise you would be surprised that some find that a foreground in perception? Because it is really bewildering that you call those cars silent - they are the opposite. A large number of electric or hybrid cars produce a whining "whaaa", a sort of synth chord, loud with a filter-pass in an abominably annoying band. I think I even heard one with a fake ICE noise (an imitation), but still a coloured timbre (not a natural noise but a synth with a perceptible note) in that same band.

And the explanations you mention really make no sense: the beeps of the backup-alert noise - which we all know were mandated because the vehicles were supposed to be too quiet - are intermittent, whereas the whine is continuous.

(The vehicles were supposed to be too quiet, so they mandated extra noises. Some of them are guessed to be nerve wracking - which is also normal in societies that have lost their natural sense.)

But look: it is absolutely impossible that I can confuse an electric car noise with that of an ICE - and it is out of question that you can allege that.

Maybe ask other people whether they hear noise from electric or low-speed hybrid cars. Really, ask other people.

Edit: at this point I thought I could sample one - but I am sure they could be found on YouTube etc., there should be no need. ... I checked: it's full of them samples.
