I use a pressure cooker frequently. One definitely wants to take the lid off with car. Right now the pressure is at the danger point. If I am in a rush and I know the stuff in it is cooked, after I take of the fire I’ll remove the little nozzle thingie (what is it called?) from the steam vent. It’s not like taking the lid off under pressure would not be pleasant.

I have heard/been around two big explosions, the first was when I was 5ish...My father was in his last year of college and we had rented a small home in a small neighborhood.
BOOM! Someone had a pressure cooker that blew up and 1/2 of the home was gone - the people were in another room and were not hurt but I will never forget it.
