'Car bloat', ‘auto-besity’ & rising sales of SUVs mean that cars are getting heavier.
Batteries in EVs add mass too. So more

from brakes?

More air pollution from tyre dust - EV cars heavier - more toxic dust in the air
Dr Chris Smith, Naked Scientists, said last year, tyre is 80% of air pollution.
Then there's the 120 tonnes of tyre dust and crumb that's used as infill in 3G football pitches

EVs use far less brakes as they have regenerative motors. The Q4 has drum brakes on the rear because it hardly uses the brakes at all - ours has done 25k miles and the brakes were at 80% wear remaining. They eat tyres though.

One of the next questions has to be about the threat the extra mass (and height) causes to vulnerable road users in the event of a collision.

Have you actually read the article you’re linking
@DrGaryFuller
?? I’m asking because in your tweet you ask: “Batteries in EVs add mass too. So more
#AirPollution
from brakes?” but the article clearly states that particulates from EV braking is significantly less than ICE vehicles

And I quote: “Despite their additional weight, the brakes in the battery and hybrid vehicles worked less than their petrol and diesel equivalents. Brake pollution was reduced by 88% in the international driving test and 68% in the London test.”
So no, less air pollution from EVs

Cars should be taxed by weight. Fairest way to incentivise adoption of vehicles that minimise impacts on roads and environment. Outcome would be adoption of small, self-charging hybrids, for most users, the greenest vehicle type

Yet you support forcing older cars off the road via ULEZ which results in more new SUVs 🤦
Also, remember it's "i" before "e" except after "c", Gaz

EVs hardly use their brakes. They regenerate when they slow down.

#evs
are bought by wealthy people trying to ease their conscious whilst getting a huge tax break but failing to understand that electric cars are not particularly green, immoral and unethical.
