It's quite clear you have no idea how long the smell of weed lingers. Also, that means you probably have no idea that when you walk around you reek of weed. Ask some non-smokers.
You seem to be confused, we were discussing smoke smell in open air not clothes smelling like smoke.
It's quite clear that you have no idea how harmful car exhaust is to myself and my children, we need to ban cars and make sure we fine drivers for harming my family
A better analogy would be, imagine your neighbor owned pet skunks and they sprayed a few times a day. Even on their own property, the scent carries and lingers. Keep your pet skunks in the house, that's all.
The function of cars can be served better by bicycles and public transport.
And no, smoke smell does not linger in open air. Molecules in air diffuse rapidly especially in moderately windy environments, I urge you to read up on basic physical chemistry if you don't believe me
The US had some of the highest rates of transmission and lowest uses of public transport when compared with Europe so I don't think that claim holds any water
Africa is not a single country, that is a sweeping statement, and based what I saw on the last time that I was in a particular city in a particular country in Africa, that statement is rubbish.
They were also taking many anti-COVID-transmission measures at the time. What I suspect is that African countries were less naïve about COVID - they had no expectations of being exceptional, of escaping unscathed, and had been impacted by other serious disease outbreaks in living memory, so they had more expectation that it was a real problem, but also one that could be mitigated.
Car exhaust is far more harmful and I don't like smelling it, let's start ticketing drivers for driving their car too close to my home
