everybody in London is breathing toxic levels of PM2.5 particles. And the fact that the largest sources of PM2.5 particles are tires and brake dust suggests that electrification is at best only a partial answer.
We also have to drive a whole lot less.
Fortunately, London appears to be pursuing an all-of-the-above strategy when it comes to greener transportation, including electric buses to a massive investment in cycle infrastructure, the goal really does appear to be easing gridlock and rethinking how we get from one place to another.
London's cycle superhighways have already shown they can deliver 70% increases in cycling, and now Mayor Sadiq Kahn has announced an entirely new, fourth superhighway bringing segregated lanes to Southeast London for the first time.
Instead of car tire and brake dust, Londoners will be able to inhale healthier bike tire and brake dust.

Yes, regen should do most of the work. I have a good friend who has had a Chevy Bolt for about 6 months. Amazingly, to me anyway, the default behavior is that the friction brakes do much (most?) of the braking. He showed me he has 3 levels of regen, but it's all based on the accelerator pedal. I would have thought a brake fluid pressure sensor, or something like that, should modulate regen braking. Anyway, if he puts it in the highest regen mode, when he lets off the accel. pedal the thing really slows down hard. I would be more gentle with the accel pedal. He loves seeing the regen watts indicated on the dash. It does light the rear brake lights when regen slowing.
