55mph Speed Limit

Thanks both. Always good to update.

Ev's do pose their own ecological issues though with the relentless mining of components for the batteries however.

Did you know that vast quantities of these components for EV batteries were mined way before for the oil industry as part of refining crude.

Mod note:

Can we please switch back to the original topic ie 55 mph speed limit.

We already have EV threads running on the forum.

Further off topic posts will be deleted.

Thank you in advance.

In the US, speed limits on main roads vary from 55 - 80 mph. The US police enforce limits more rigorously than the U.K. I think in the U.K. we should be less rigid with the uniformity of limits, for instance the M6 through Birmingham could arguably be 55 mph, but north of Manchester it could be 80.

Salisbury was one of the first IN THE UK to implement a 20 limit, complete waste of money as it’s almost impossible to get up to 20 mph.

Just need a bit more thought

Police in the US do NOT enforce speed limits strictly, but the only thing they do write tickets for is speeding, and you have to be going 15mph over to get a ticket.

That’s not what we saw and heard when we spent a month riding a motorcycle over there and our friends in Mo tell us, but as with all things in the US they vary greatly between state, county, city etc.

Back in 1979 my mate got pull over for speeding in Yosemite which being a National park meant he was subject to Federal law rather than California state law. I think once convicted it was either $50 fine or clean toilets for a day, he opted to clean the toilets.

But far less so than ICE vehicles. The regenerative braking offsets any extra PM 2.5 that would be produced by the extra weight, and the noise is far ess than ICE, so the main difference is the tailpipe emissions.

Not sure about that. Bigger batteries and cars increase tyre wear yet brake dust might be the more dangerous PM 2.5 of the two.

And there is much less brake dust from EVs. They hardly use the actual brakes at all except in emergency stop situations. Yes, there will be some extra tyre wear from the extra weight, but as I said, I think the severely reduced brake dust offsets that.

I have read reports from mechanics that they often find a significant amount of rust on the surface of EV brake disc as the things go for ages and never use the brakes much if driven gently
