You are correct. But in my area, driving rules and etiquette had been breaking down for years before Covid, before
defund police’, etc..
Many people just don’t give a damn about other people anymore, and don’t think that they have any duty to be civil.
I tell you — the one place I ever see cops anymore is on the highways, patrolling and monitoring speeders. Coming back from our Easter trip we saw one at least every 10 miles.
We are seeing that in North Idaho, too. It was the most civil, polite place you could imagine before it was discovered.
