EVs 'cause TWICE as much road damage as petrol equivalents'

More negative EV press today, this time they're to blame for the state of the roads. Given there are still a very small amount of EVs on our roads, what's the reasons they're in such a state now?

Well it is almost true: they are heavier than their ICE equivalent car and will cause more damage as a result. However most ICE cars are SUVs and are heavier than the saloons/estates/hatchbacks they replaced en-mass so the problem isn't EV to date but they do nothing to help the situation and will make things worse as their numbers increase.
Massively oversimplistic analysis
I’d be amazed if the reduction in torque spikes from the engine and gearshifting in particular didn’t at least cancel out the impact of the extra weight
Great example, there’s an HGV MOT centre near us on an otherwise lightly used and well surfaced road without much else situated on it for a mile or so in each direction. There are patches of potholes that correspond to the typical gear change points where all the trucks are accelerating out of the entrance.
Same on the way down the hill to the roundabout before it, the rest of the road is perfect but it gets absolutely obliterated in 10 yard patches where all the trucks are slowing and downshifting

You do (at the risk of being labelled a tin foil hat nutter) have to ask, where are all these anti-EV stories in the press coming from? There's a steady stream in the Telegraph and quite a few in the Sunday Times as well.
They all fail even basic levels of journalistic balance and care and so you do wonder what the motivation is. Big oil have deep pockets to fund media campaigns after all.
The trope about tyre wear before anyone mentions that has been largely disproved. Kerb weight is not the only factor, the smoothness of the drive train has a lot to do wear tyre particulate production as does the use of low rolling resistance tyres that are commonly found on EV's. In addition, brake particulates of course are almost eliminated by EV's using regenerative braking.

There was a post by a road engineer who wrote a long post about this. If someone can find it, it should probably be a sticky.
He mentioned (among other things), that passenger vehicles are completely irrelevant for road damage compared to the weight of trucks.
And yes, these Anti-EV articles are getting very tedious. What about the rise in home delivery vans, for example?

Weight has a big effect, because it scales with the fourth power of weight over the axle - but if a light car is like a gnat bite, a heavy car is like a horsefly bite, and an HGV is like a mauling by a shark.He mentioned (among other things), that passenger vehicles are completely irrelevant for road damage compared to the weight of trucks.

The article might as well read "cars that give your kids less cancer wear away the road surface marginally faster than the cancer cars - should we ban them!?"

I must admit I’d noticed it as well, particularly the Telegraph, although I’d put it down to s
t stirring algorithms trying to goad some clicks as Google probably ‘knows’ I’ve just bought an Electric carLogistix said:
