I have done that more than once in my life - especially as I get older! It last happened when I was tired after a hike in NH. I tried to open a door of a car that looked just like mine. It only lasted a second before I realized what I was doing. This was open carry no license MAGA country, so my first thought once I figured it out was, what could have happened if the owner saw me. It was maybe an irrational thought...but maybe not.
