London Pollution, blame the wind, not the cars
Wind is more responsible for Pollution than Cars in London.
When wind comes from main Europe or The North pollution is 2x that of when it coms from the Atlantic or West Europe. Fortunately 64% of the time wind comes from Atlantic or West Europe.
Last weeks wind resulted in PM2.5 >70 which is like smoking 2.5 cigarettes in 1 day. This is easy to avoid with a cheap mask whilst commuting.
