Seriously. I’m from texas. Some people would happily let him come over to their car and start reaching in punching just to let it cross into castle doctrine/stand your ground territory. I was always taught to just assume people have guns in their cars and to act accordingly.
I would also encourage people to go to midnight showings of Tommy Wiseau’s ‘The Room’ and watch as people throw handfuls of plastic spoons at the screen. Also fun.
