I do live in a city and one of the biggest issues is cars park on both sides meaning there’s only room for single traffic meaning a lot of cars meeting and reversing.
I have noticed the anger and rage, mouthing obscenities and hand gestures because someone else happens to be there.
I get the inconvenience of having to pull in or reverse back but I would never feel the need to aggressively stick my fingers up (or worse) or mouth something at another driver for simply using the same road.
I’m sure these people aren’t like this in their homes or businesses.
