I wonder if anybody else has noticed, especially cyclists, like me, the sudden increase of vans and other vehicles polluting our breathing space with diesel fumes.

This burns the nostrils and is not acceptable healthwise.

Buses used to do it, now it's white vans. It takes time for the fumes to clear from a street.

Oxford already has an air pollution problem already and these diesel fumes are nasty. The problem needs addressing.
