Pollution speed limits everywhere not just Wales

[saaby93]

A few papers reporting speed limit reductions for NO2 this morning

That wont apply to leccy cars?
Would it matter if safety goes the other way

[Castrol for a knave]

The M1 just south of Tinsley has a 50 mph speed limit for around 3 miles, citing "Pollution Reduction".

I wanted to blatt through at 70mph in the Tesla, but didn't think the magistrates would be understanding.

I am not sure what they are trying to achieve- maybe some air quality monitoring exercise.

Thats surely the way to encourage EV takeup, 50mph pollution limited speed for ICE, 70mpoh for EV?

It's a joke though, 10-20mph 6 mile queue on sunday leading upto the newport tunnel...

The biggest joke is the western end of the A40 which has a speed limit reduction. Fair enough, except that it runs between Heathrow , ( second busiest airport in the world , normally), and RAF Northolt which seems to cater for private jets and the odd RAF plane .

Why isnt Northolt considered Heathrow 3rd runway?

Queens flight?

50 is the new 70

That was there pre-COVID. I presume that they removed it during pandemic times as the amount of trafic had decreased.

Just speculating but how about a blanket speed limit of 90 km/h (56 mph) across the whole road network, except where lower limits apply? Safe with low emissions as we would all travel at exactly the same speed including HGVs. Only a few mph slower than 60 so no significant penalty.

Seems the obvious next step

Take it to the logical conclusion & we can solve both pollution & unemployment by reinstating the men with the red flags.

It's a tiddler, so it would be Heathrow's 2½th runway. The regionals had been sniffing around it pre-COVID, but the world has changed.

No.

They'll find another 'reason' in that case, perhaps brake dust.

We'll use EV hovercrafts and it'll be fan noise.


There's always a 'reason' to limit speed, for some reason govt seem determined to bring the man with the red flag who used to walk in front of cars out of retirement.

They wouldn't be the first. The Dutch have a national 100kph limit during the day, reverting back to 120/130 at night. It must actually make a pretty big difference to pollution, I average at least 10% better fuel consumption during the day.

Presumably your time costs nothing ?

A notional 100 km journey at 100 kmh takes an hour. At 130 kmh,
it takes 46 minutes.

Even at £20 an hour, that's £4.70 time saving. Compare and contrast that
with a few pennies saved in fuel.

Do the same journey in Germany at a leisurely 150 kmh, and that
100 km might only take 40 minutes, or a £6.70 time saving.

We can easily see that the Dutch are wasting a lot of time and money
with their limits. The German way is faster and cheaper.

[RizzoTheRat]

But time and money aren't the issue, they've introduced the limits in an attempt to meet their emissions targets. They have more than double the population density of Germany.

They are wasting your time. Is that really a problem? If you work longer hours to get your job finished, there is zero impact on the Dutch economy. Sounds like win-win to me from their government's standpoint: emissions reduction without any penalties

Twice the density they may have, but the Dutch are about 0.23 %
of the population of the world.

The main world polluters are China, USA, India and EU. Getting all those
folks to reduce their pollution would be a good thing, fiddling with 0.23 %
of the problem and ignoring the 99.77 % looks remarkably pointless to me.

I have always found a lot of irrational debate in climate change circles.
Indeed, some religions make more sense to me.

And yet the same limits apply to EVs. I suspect somebody isn't telling the whole truth.

Dutch issue is their local air quality does not consistently meet EU standards:

Climate change is a religion in some circles. Are you questioning the faith?

You can't handle the truth
