Cars spread pollution in many mysterious ways, take the tires for example" According to a 2017 study, about 550 tons of airborne particles from tires are produced annually. Further a study released in July pointed to tires and brake pads as the source of about 550,000 tons of ocean microplastic emissions annually.5 Oct 2020 - Microplastic pollution has polluted the entire planet, from Arctic snow and Alpine soils to the deepest oceans. The particles can harbour toxic chemicals and harmful microbes and are known to harm some marine creatures. People are also known to consume them via food and water, and to breathe them, But the impact on human health is not yet known. Earlier work suggested microplastic particles could be blown across the world, but the new study is the first to quantify the effect. The scientists concentrated on fine tyre and brake dust as there is better data on how these are produced than tiny microplastics from other sources, such as plastic bottles and packaging.https://www.theguardian.com/environment/2020/jul/14/car-tyre... |

So busses, semis, trucks and other rubber tired vehicles are also a no go.

This adds other wheeled vehicles which use friction based braking into the equation.
I intentionally exaggerate the tone of my comment, but it shows a much bigger problem: All kinds of transportation has some serious impact on the environment. So just taking ICEs or cars out of the equation doesn't solve the problems magically.
We need a much bigger vision and a set of solutions which addresses these problems.
