Exhaust noise? Very few mainstream cars actually make any  now , and even when they did most cars (Alfasud, Ford and Alfa Twincam et al  excepted*) sounded awful . Stuff like AMG Mercs make an absurd amount of noise and bluster, as do any sporty Jags and ..err..Astons but if you are over 13 they just sound silly.

For me the first principle should be not to disturb other people. That goes for exhaust noise on public roads in exactly the same way as for loud music with the windows down (or in neighbours' gardens without the appropriate precautions).

But:

  1. We may need sound generators on future vehicles to warn of their presence. I've seen mention of turning this on automatically below 30 kph. But it would be one of the easier functions for smart detection systems.
  2. If you want loud sound in your own car whether exhaustive or musical you can run it through headphones etc. And it was Lotus who originally came up with the technology for making whatever engine you have sound like whatever engine you want...

The weird thing is that engine noise has been a huge source of pleasure on track, strip and  stage but much as I enjoy the Seven's bark and pops , they are only to be indulged when I am not going to wake people up , scare them or their horses or pets . I honestly do find some of the daft levels of noise from AMG Mercs especially  crass, antisocial  and infantile . One overtook me on M1 yesterday and it sounded like a bloody Can Am car , but tragically it didn't look like one - just another pumped up , willy waving saloon car on steroids .

When we purchased a new home in 2001 our local council had pretty much abandoned requirements for parking spaces.  We thought this was crazy - most homes are now 2 cars ++ and they have to be parked somewhere.  I asked the council rep about this and he said that by removing the parking space requirements they were hoping that it would encourage more people to use public transport Silly

The new build that we are buying now has specific conditions that ban use of solar panels.  It will be interesting to see how the Tesla Solar Roof system performs.  I've heard stories of 'incidents' where ev owners have tried to use class 2 chargers at home and either they or their contractors have messed up the work on the circuit breaker to get a 240v supply.  Wooden houses and dodgy electrics are not a great combination Eek 

Our builder at the place we are buying now had to prove his 'green credentials' to get planning permission.  He has fitted LPG (even though mains gas was available) along with a combi boiler (still a bit of a novelty in the US) with hydronic (radiant) heating for the ground floor.  The combination of the three is meant to be 20-40% more efficient than a furnace with radiators.

Isn't it fascinating how other countries approach the same problems?

I'd never heard of "hydronic" heating. But it looks like traditional British circulating hot water systems... what's the difference?

Yes. There's quite a lot of that around.

That logic is OK... but only if there's an integrated transport policy.

Traffic and parking was by far the single most important planning issue for the new "hospital" builds in Oxford.

A few more details of the new London cab.

The design doesn't sound right to me...  70 miles range on batteries, average driver's day of 120 miles*, need to operate in highly polluted areas with increasing restrictions coming soon. That might have been better met with an option that had bigger batteries and lost the range-extender engine and fuel tank...

* How long do London cabs operate compared to drivers? Are they still owned by individual drivers?

Black cabs:  https://www.theguardian.com/business/2017/jul/11/black-cab-turns-green-new-electric-london-taxi-levc-tx

I think the range suggested is pretty poor. If an average driver covers 200 miles per day  http://www.telegraph.co.uk/finance/newsbysector/transport/10572289/New-electric-black-cab-could-save-drivers-200-per-week.html   then by recharging over lunch, you don't need the petrol engine.

Modern EVs have ranges of nearly 200 miles per charge and will charge in an hour.  Given that a black cab is a good size, the design should easily be able to have sufficient storage to match small vehicles such as the Zoe or Leaf.  After all when the cab is stationary, no fuel is consumed.

And the cabby gets cold in winter, poor cabby.

Talking to a very knowledgeable Euro man at the 60th, he said the future isn't so good for electric. It takes an enormous amount of earth/lithium to get enough to make a small battery as it is. The amount of effort required for that alone is immense so if a country called Volvoruritania goes over to it it would make a very big hole. If the rest of the world does too it would take most of the planet. Best get another planet rich in the stuff first he thought...
