"Super light electric bikes could soon be a reality..." ??

I'm not trying to change your mind flecc - that clearly won't happen.

The only noise I get is from very poor road surfaces.

Sound dampening material around the cabin would reduce noise of wheels hitting poor road surfaces from entering the cabin, like they do on the Royces. Heavy, will reduce range.

Overall I'm completely against adding any noise to anything, we've made this world far too noisy already, from damaging our own hearing to killing cetaceans

What we're doing to whales with shipping noises and ultra-loud sonar in military vehicles is cruel and unnecessary. But we're talking about electric cars noise in urban environments, inhabited mostly by humans.

It wouldn't be difficult to install human sensing systems for the emission of warning noises - cameras at all sides and a little AI taught to recongise human and animal shapes, then sounding an alarm of appropriate frequencies for whatever species your silent car is about to run over and kill (or maim and/or dismember). Much of the work has been done while developing the fatuous effort toward self-driving cars, although most ise LIDAR, others use purely image-based recognition using human visual range cameras.

Exactly as I've already said, useless. But as also said, that can't change without international aggreement on a single standard sound. The present mix of all manner of sounds at a sufficient volume to warn would be unbearable noise pollution, hence the legal requirement being so low.

The sound does need to be much louder. High performance petrol engines sound like Sabre-toothed Tigers anwyay, which helps, but they're extinct and cannot be directly sampled. My personal theory is that the threatening sound of Sabre-toothed Tigers (and anything like it) has become embedded in genetic memory, just as the fear of snakes and spiders have.

The population need to be made to understand that owning a car is not a right but a valuable privilege that can be lost at the first sign of any anti-social behaviour.

Such as turning off the audible noise on an electric car that it was manufactured with...

Very undesirable of course and a completely wrong approach, curing the symptom and not the cause.

It wouldn't be difficult to install human sensing mechaisms for the emission of warning noises - cameras at all sides and a little AI taught to recongise human and animal shapes, then sounding an alarm of appropriate frequencies for whatever species your silent car is about to run over and kill (or maim and/or dismember).

Already done, like many, my car has radar, four way cameras and eight sonar sensors around it for detecting foolish pedestrians and the like. And when detected the car alerts me with warning sound codes and when necessary if time is short, it puts its own brakes on to stop in time. The latter very rarely happens since I'm a very alert driver, it mainly occurs for false alarms caused by the car not understanding what is happening.

And also manufactured with the off switch that has to be used by law at present.

I doubt you will ever learn. It's a sound which doesn't and cannot do what was intended, both as I've proven and as pentium has remarked about how uselessly quiet it is due to the law.

There is also anti-sound, which is lighter and uses very little energy. The best thing is, it's not vapourware technology - already in many a brand of headphone:

The challenge would be modelling the interior cabins (which have many different surfaces with differing acoustic properties) to nullify undesirable sounds completely. Headphone interiors are far easier to work with.

Exactly - you just need speakers outside your silent electronic death chariot (all sides) to warn pedestrians too, which I'm sure you'll resist the installation of, to the hilt.

If it doesn't warn hedgehogs, it's a crime against nature.

I'm sure the pedestrians would resist too, all those noises coming from various cars!

As with all cars I have a horn for warning others of my approach, though as a responsible driver it virtually never gets used since it's not needed with good driving and the same goes for automated sounds. I'm not bothered by all the false alarm sounds I get since I understand how deficient our AI is at present, but I doubt pedestrians would be so understanding of unnecessary and unexpected loud noises.

Ours is a badger area so they don't live to reach roads.

Again, I'm not trying to change your mind: Speaking as an elderly and (slightly) visually impaired pedestrian of many years, I welcome the prospect of non-silent electric cars, unlike those Nissan Leaf taxis frequently shocking me with their sudden appearance - particularly since taxis seem to be only driven when their drivers need a nap. I don't care what it sounds like, as long as I can hear it... but I favour the sound of Doberman growls. That really gets your hackles up...

Badgers run over the roads all the time here - it'd be one hell of a thump if they hit a car, and dangerous for the car's occupants, I would have thought. Let's hope the next generation of pedestrian sensing systems are designed to protect general wildlife, unusually shaped and/or deformed humans, and those with a non-standard number of appendages.

Much of what's termed as Artificial "Intelligence" represent "Learning" systems; only as good as the data they are taught with, and the speed and magnitude of real-time processing. That data will only increase in quality and scale... as will the speed and viability of the processing of that data, at a low enough price point (and small enough) for the GPU/CPUs to be included in the design of ecars. Therefore there is hope for the future, until the global threat of real AI arrives.

We get some run over. I tried to save one of twins that was run over as they followed the sow crossing the road, but it was too badly injured having lost all its hind quarter use.

My sonar does pick up things as as small as badgers and foxes or any shaped human, but I think hedgehogs would be beyond it and squirrels too quick and eratic.

I see badgers running around all the time on my way home, they are legion around my house... and it's awful to see those mad little bears dead by the side of the road. Hedgehogs: let's not go there. Using a shorter wavelength than infrared might be better at detecting smaller animals.

we could make the speed limit 200mph in the slow lane

That's sad. Gosh I hope I never encounter an injured one, I'd have to do something to try and save it.

I'm all for caged off roads! With aerial walkways, cycleways and wildlife crossing paths. Better still, let's put roads all underground - electric cars won't gas people to death in tunnels under cities and countrysides, hedgehogs and other wildlife (apart from rats) would be safe, lift platforms could move cars into car parks under supermarkets, warehouses and workplaces, people could drive at crazy adrenalin pumping speeds killing each other, pedelecs and pedetrians only above ground - in greenery strewn cities without cars or lorries of any sort visible. Yes, lets.

so when are we going to get a electric cargo ship then, not going to happen is it not buy 2030 anyway pmsl.

South Gloucestershire could be home to world's first nuclear fusion plant

Bid to build nuclear fusion plant in south Gloucestershire

A world-first prototype could be developed at former nuclear power station sites

and when did we make that work ? and what happens when it catches on fire.

It's flaming pie in the sky mate. The worst is that they could actually set the whole sky worldwide on fire burning everyone and everything- something they were worried about with the first nukes.

they wont work on a cargo ship lol
