Well …I’ve probably forgotten some of the close calls and was thankful maybe I had some angel around.
The number of close calls for serious car crashes have been numerous in all my years of driving including in Metro Washington DC, Philadelphia (where I live now and work though my commute avoids the hazardous freeways and center city), Tampa Bay, Atlanta, and Las Vegas.
One episode in Las Vegas comes to mind at the very least.
One night at work, a gentleman with whom I spoke casually turned out to be a mentally ill patient. He surrendered to me, without any expectation or request, a large knife to me before checking into a hospital for care.
I was armed with a firearm, but in that sort of situation something can trigger (no pun intended) such a person in an instant because they are ill.
I learned so much from that event about how to try to work to help even people in great difficulty yet to always be on guard.
