As a foreign tourist in london, london needs to fix its infrastructure. The amount of fine dust in the tubes is criminal.

Pandemic or no pandemic, wearing a high filtration respirator (N95/FFP2 mask at a minimum) on the tube, where air pollution levels regularly exceed Beijing and Delhi, is advisable. Also sensible on inexplicably still diesel choked busy London streets above ground.

Streets are getting considerably better thanks to ULEZ and all the horrible busses and taxis being replaced.

Yeah tube dust is nasty. I’ll give you that. I barely ever use the tube now preferring to use overground trains and walk if possible.

A lot of people don’t seem to know that a lot of tube journeys can be done in a few minutes on foot.

While I'm skeptical of the UK govts 2030 ban on selling combustion engine vehicles, I think going electric may the answer to London air quality.

Correct but only because people won’t be able to afford to replace their old cars with electric ones.

I can well believe it.

While I spent the pandemic in Berlin and didn’t notice much change here, 20 years ago I was in the UK and the daily walk past the A27 was radically improved by the truckers blockading the entire UK petrol supply in protest against fuel taxes.
