Not sure many in the natural world would be wearing hearing aids which was the question started off by your post #115.Somehow I doubt that most of the noise on cars comes the tyres? Most diesels can heard anytime of the day. Best time for anyone to check is a night when it is quiet and hearing aid is switched on.
In case you miss it I was referring to a human being standing next to a car at night with the engine running which is why i mentioned that it is unlikely that tyre noise on most cars will be louder than the engine. However thanks for putting a twist on the tale!
Others may say different but searching the net tyres don’t come out as the main culprit.

In the first paragraph of the paper it refers to the noisiest place IN the car. That is not entirely relevant as its the noise heard as the car approaches that would alert wildlife or humans (is there a difference ?)Others may say different but searching the net tyres don’t come out as the main culprit.
What do you think Prof? Personally all academic to me but the Guide dogs Association seem to know more😉Analysis of Noise Levels in Typical Passenger Cars
Passenger cars differ in their levels of emitted noise and mileage, which can have a negative impact on the environment and humans. This was confirmed by the results of this study on the noise levels generated by passenger cars that have the same parameters, or are of one type. The loudest place...
This paper only looked at stationary cars, so I would expect the tyre noise to be imperceptible.Others may say different but searching the net tyres don’t come out as the main culprit.

Even without the hybrid battery the CRV is quite a sizeable car, and I guess he has the one with the 1.5 VTEC turbo, which whilst a nice engine isn’t renowned for being frugal.
A non hybrid petrol would probably be a lot less mpg.
As others have said the ICE CRV's aren't known for ground braking fuel efficiency. and the typical battery used in Hybrids only weigh between 100 and 150kg so similar to two adults.
Can I assume you mean "breaking" rather than braking as I believe that when braking it sends a charge to the battery? Although the battery may weigh between 100 -150kgs when you also add in the weight of the driver it makes a difference.
If they were compliant with the 30 mph speed limit they'd have been on little more than tickover with very little throttle used.Were the diesels and petrol cars coasting past in neutral?
I would think less noise would suit shy wildlife? They'd be able to hear their surroundings much better, and of course they use eyesight / scent to warn themselves of any dangers.
I wonder what the cost of repairs and parts will be compared to your Touareg?
Touaregs aren't cheap to repair either - but then it's not a cheap car.
My V90 has developed a parking sensor fault which also affects the rear auto brake/collision avoidance system. It went in a few weeks back and they swapped sensors around, problem still there. Last week the tow bar refused to fold out and I kept getting a "trailer bulb failure warning" even though I wasn't towing,. The tailgate also started to close on its own when in the open position. On Saturday the tow bar issue disappeared and the tailgate is behaving. Part of my job is electrical engineering and a lot of this does sound like moisture ingress somewhere, it went back to Volvo on Monday morning first thing, on collection the parking sensor issue is still there and they admitted they couldn't find anything wrong with the tow bar/tailgate, BUT they had "updated the software" to see if that cured those problems.
Regarding updates, if the consumer has a laptop at home why can't the consumer do exactly the same thing that the garage does and download the software into the car instead of being charged £100's by the dealer to do the same? After all isn't that why modern cars have extremely easy user interfaces?
Better buy a Kia then as my updates are free until 2029, not via the air, but I download onto a 64 gb usb stick then insert into the cars data port and it then updates. But these updates wouldn’t help Gary as they are only for Infotainment and Navigation, and some control functions.Regarding updates, if the consumer has a laptop at home why can't the consumer do exactly the same thing that the garage does and download the software into the car instead of being charged £100's by the dealer to do the same?

I wish I could update the Satnav in the Jeep for the odd occasion it is required as it is still a 2017 version although the vehicle is a 2018. Dealership want over £400!
Have a look at SatNaviShop - I've used them twice to update the satnav on my VW Touareg - they include maps, software and firmware updates - the guy who does the VW/Audi ones is based in Lithuania but his English is as good as mine and the instructions are spot on.
