#2I'm glad that they address the increased tyre wear pollution. I'm not entirely(!) convinced that EVs only have slightly increased wear as there seems to be plenty of reports of EVs going through tyres a lot quicker though estimates do seem to vary from about 30% to 50% more wear.
(Also great that the report mentions the importance of walking/cycling for city transport)

#3Brake dust is such nasty stuff, yet we place schools and homes right next to the rivers of pollution that we call highways. I'm hopeful that we will legalize the building of less car-dependent housing, but until then at least EVs will help.

#4To those wondering about tire wear:
"Despite the slightly higher levels of tire wear from EVs, brake dust was found to be more unhealthy, as brake dust is much more likely to become airborne (>40%) than tire wear is (1-5%). So EVs create a lot less of the worse thing, and a little more of the less-bad thing."

#5> It turns out that BEVs (battery electric vehicles) reduce the amount of brake dust by 83%, according to a new analysis by EIT Urban Mobility (a body of the European Union) and Transport for London. The study looked primarily at London, Milan and Barcelona.
> The primary reason for this is the use of regenerative braking, meaning that electric vehicles can slow down without rubbing friction brakes. Other vehicles that use regenerative braking reduced brake emissions too, with Hybrids reducing them by 10-48%, and PHEVs by 66%.
Technically not cleaning the air as the title says, but still a major improvement.

Do you know where the increased tyre wear comes from? I run a PHEV, and if anything, my tyre wear has improved.
This being said, I’ve noticed that many a “big EV” driver will take off from red lights like they’re driving a dragster.

That would be my guess. Occasionally looking at specs from EV's coming on market, they seem to have very powerful engines, and of course the torque curve of electric motors is fantastic. So if you have such a car, and a heavy foot, I can well imagine you going through tires at a decent clip.

Extra weight because of the battery, I think. Our EV is light for its size, but still 50% heavier than our previous ICE, of a similar size (Renault Scenic e-tech, 1.8 tonnes vs SEAT Leon ST, 1.2 tonnes).
Though the additional acceleration probably does also make a difference.

Increased tire wear comes from the weight of the car and cornering. The tires need to do significantly more work in accelerating (the centrifugal kind) a car around corners at equal speed.
