Answer 1

Rubber from tires, material from brake pads/rotors/drums, heavy metals like palladium platinum and rhodium from catalytic converters, and any fluids that leak out all end up as dust/debris on the side of the road, being blown around the environment and washed away by rain.

Motor vehicles are dirty pollution producing things. There are regulations, testing and (admittedly lackluster) enforcement in place to keep these things below a certain level, but there’s only so much you can do. Especially with how much our society depends on transportation.

Just another reason why public transportation and car pooling instead of everyone taking their own personal vehicles is a good thing.
