EVs produce more tire dust, but much less brake dust and exhaust (even when powered by coal plants).

The net effect is a massive reduction in dust and particulates.

Some modern tire additives are incredibly toxic to fish. They’ve been banned in the EU, but for the very special corner case of driving in sensitive watersheds in the US, it’s possible EVs are worse on that one dimension.

Of course, we could just ban the recently approved additive, and completely solve that corner case problem.
