Even more to this, regen breaking is only really limited by amount of current the battery pack can charge at (hence why regen sucks on plug-in hybrids with their little battery). As battery chemistry gets faster charging, regen breaking will get more and more powerful. With those solid state batteries some manufacturers are working on, you might not even need friction breaks on the car at all.

Tire dust though, evs solve nothing and are actually somewhat worse. They tend to have a lot more torque, and are currently somewhat heavier than an equivalent ICE car. Materials science will probably be able to give us incrementally less toxic tire dust, but only if there's pressure to invest in R&D.
