Re: 50 miles???
"Brake and tyre dust make up (IIRC) around 40% of the particulate emissions of a petrol engine car."
Brakes rarely get used in an EV with high ReGen, say a Tesla Model 3. The brakes will last many times more than they ever would on a ICE car. Tyres, probably wear slightly more than average due to desire to accelerate a bit quicker than usual. This doesn't seem to have been taken into account with EVs,
Also noise pollution is greatly reduced.
