60MPH over 70MPH is the difference between 28MPG and 25MPG for me - so it does make a difference over a long run.
Can't say I've sat at 70 for a long time now - I find it much more relaxing following stuff pottering along in lane 1 with an audiobook.
Old age is creeping up on me

A pre 1992 truck will have a 60mph limiter.
Well yes that's cool and all, the 90kmh detail has come after clarification it's instructed as per an EU mandate - however my questions arose from the absence of that information here: https://www.gov.uk/speed-limits
Absolutely - I’ve already acknowledged that - and these limits are for air quality at point of use, so that argument does not apply to EVs because the emissions they undoubtedly do cause are a long way away.
But that’s not what we’re discussing here. And EVs have harder low rolling resistance tyres for fuel economy and they use their brakes significantly less because of regenerative braking so your argument is still exceptionally weak.
Nope, those that had limiters were set to 56mph as well.
I so recal driving an 87 E plate Mercedes 17 ton rigid back in the day that had no limiter it would happily do 80+ - although it was a wreck we used to fight over who got it for a shift because it was unlimited.
fairly sure limiters became mandatory around 1989 but can’t find a confirmation.
It's not? I thought were talking about lowering the speed limit to increase air quality, my mistake.
Not air quality from brake dust or tyre particles. Exhaust emissions. From ICE vehicles in the local area. Or did you not read the OP? It’s about NOx emissions.
And yet people are also talking about heavy goods limiters. You carry on thinking EVs are the bees knees after all your saving the planet.

I'd imagine that EVs running at 60, save more battery than at 70, so better for the environment too, that electricity has to be made somewhere.
Wow! If that’s a Zing! In your world you must have a very disappointing life.
What argument were we having again?
You can always tell the overly defensive one when they take offence at an obvious play on words.
Yes. That’s a valid argument. The difference between 60 and 70mph in most EVs is massive. Maybe 25% less efficient. And that argument will just get you a blanket 60mph speed limit rather than a localised one. I wouldn’t use that argument again in case someone wakes up to that particular fact.

I shall use it to smite EV fanboys everywhere!
