You are welcome to edit your comment to clarify.

No need, it is correct.

Bikes have tyre pollution, and trains have brake pollution. Seems like a pretty simple statement to me.

Interesting that you have moved from arguing the point into semantics now without addressing anything else. You are welcome to remove your downvotes.

People seem to get very upset when others point out that transport like bikes and trains still cause the same pollution as cars. yes it is much less, possibly orders of magnitude so, but they still cause it. Perhaps instead of getting the pitchforks out we could work together to find better wheel and brake solutions for all transpotation methods which dont cause so much toxic dust.
