That in the UK most diesel drivers remove their particulate filters to increase fuel efficiency (meaning that essentially every white van on the road is rolling coal like a Texan), makes it all the worse.
It's not even the lung damage, the brain damage that's been caused (there's ongoing research that may yet associate the spike in autism and neurodegenerative diseases in Europe with diesel exposure since it was incentivised) could be even more prevalent.
Margaret Heffernan did a willful blindness Ted Talk about this just about ten years ago that really rings true on this topic.
