- kibwen 4y agoKeep in mind that EVs with their regenerative braking use their brake pads effectively never. Modern EV brake systems actually have to deliberately not use their regenerative braking once in a while in order to exercise the brake pads and make sure that they don't rust into uselessness from utter disuse.

- elsonrodriguez 4y agoIt’s also important to wonder how much of the pollution is leaked fluids and burnt motor oil. A while back I saw a video on youtube of someone mining road dust for platinum of all things. Evs will be a likely improvement for the health of those near roads.
