A trial on stretches of Motorways in Wales is now to be made permanent to reduce pollution I wonder if this will come in force for the rest of the UK

In France they often restrict speed on their motorways when pollution exceeds set limits. However this is used much as our "variable speed" sections of motorway are used i.e. as and when needed. It seems a little draconian to enforce it permanently.

No. Calm down.

On my rare forays on the UK Motorway system, I believe it is fortunate if one can ever achieve 50 MPH!

M23 from the M25 up to Crawley is 50mph for the next 2 years while they put a smart motorway in place

I heard one person on the radio say apart from the pollution, the theory is there should be less motorway accidents so traffic should stay free flowing more of the time.

Absolute rubbish, just want to raise revenue. How can one test out a 180mph car now?

Nice theory but I doubt it would work
Incidents ie animals jay walkers objects falling on the road/motorway etc can’t be dictated and usually leave a nice long delay and I doubt many switch there engine off waiting

The most efficient speed on the cars I’ve had tends to be 55mph. If pollution was the reason that’s a more sensible limit. Though that’s only based on the cars I’ve driven, others may be different.

The most efficient speed of cars is 0 mph.

55moh is the optimum speed for best mpg, this applies to all cars.

That being the case then motorway speed limits should be 55 mph unless the thinking is that setting it at 50 mph means most people will add a little when driving.

It’s statistically proven that the faster a car travels the safer it is. I’m not advocating 100mph, but certainly more than 70.

Do those statistics simply suggest motorway driving results in fewer accidents than other roads that have lower speeds. More to do with the type of road rather than the speed of the road.

This obviously can't be true, so Prove it.

Tfl in their speed, emission and health document, says that 55-60 mph is the most efficient and therefore the least polluting.
I am sure if you dig deeper, you will find the research.

Perhaps on average, but not ALL cars.

Yes all cars, it’s the most efficient speed a car can run at. It’s why all cars mpg are measured at 55mph

What about a car that can't reach 55mph?

I don’t think I know of a car that can’t go that fast!

Pretty much ruins your silly statement.
Need to be an engineer or scientist to properly understand why.
