Tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food.
Technically, a subway would be easier to build a microplastic containment solution than applying the same to endless miles of roadway. Using metal wheels is probably still the better option though
My city’s metro system uses rubber tyres, :(
I imagine it’s still orders of magnitudes better than everyone driving their own car in.
Same with busses. Don’t let perfect be the enemy of the good

subways are only economical in big cities though.
No one is building a subway in my town, would be waaaaay to expensive. they couldnt even keep a tram system going
