I want the future to focus more on the brakes and tire dust, and the increase in cancers and other problems by people who live near busy roads or highways experience. Nobody studies this, and combustion or battery, everyone is affected by it. Even playgrounds are filled with shredded tires, which borders on biohazard.

It gets studied. EVs are often heavier, which is worse for tire wear, but use regenerative braking, which is better for brake dust.

Overall, EVs are likely a net win on the combination of these two things, and a big win on exhaust emissions, but it would be nice if we could shift to lighter and smaller vehicles and increase the mix of non-cars such as e-bikes and mass transit.

EVs should do much better on brake dust thanks to regenerative braking, no?

They don't study it, but you're worried about it? I'm curious to know why these things in particular (brake dust and rubber tires) are on the radar.

(And a quick search shows that people do study this.)

The best solution is to build walking or biking environments.

We need to start taxing vehicles based on the damage they are responsible for. The 4th Power Law is a principle in road engineering that states that the damage a vehicle causes to a road surface is proportional to the fourth power of its axle load. This means that even small increases in axle load can cause exponentially greater damage to the road.

A Prius causes about 50,000 times more damage than a bicycle.

A truck causes 16 billion times more damage than a bicycle.

A truck causes 31,000 times more damage than a Prius.

The solution is to tax trucks 31,000 times more than cars. Improve walking/biking/trains/public transportation. Private cars should be a luxury which is made a necessity with zoning laws.
