I really noticed how much better the air near me (in the UK) was during the first lockdown, when there really wasn't much vehicle traffic in the suburban area I live in. I go for a walk every morning, and the air was noticeably better then. As the cars started to reappear, I began to notice just how smelly they are. I now have an EV as my family's main car, and it was driven in part by this (obviously obvious!) realisation.
