Yes, but it turns out it doesn't matter much.

What _does_ matter is the huge reduction in the much more dangerous brake dust, as electric vehicles convert the kinetic energy back to the battery charge via generation instead of wasting it via friction: https://news.ycombinator.com/item?id=44666157

Would hybrids also have the same advantage? I have 2 hybrids as I have use cases that need gas (rural driving). One of them is a traditional style and the other is a 50 mile electric option which can use gas when needed.

This comment says EVs generate 10-15% more tire dust which is a significant ocean pollutant.

Does anyone know the impact on human health?

The comment is that they’re 10-15% heavier, not that they generate 10-15% more tire dust.

In general tire dust generated seems related to tire compound (softer tires = more dust) and weight of vehicle. Although EVs are heavier, they also tend to use harder tires for more efficiency, so it would not surprise me if it’s a wash by equivalent tires to whatever is used in normal combustion cars.

Seems to me the focus for tire dust should be focused on the truly heavy vehicles: how much do 18 wheelers generate, given they’re typically weighing 10-40x what a regular car weighs.
