The best gunfight is the one you don't have.
Retreat into the dark, behind shrubbery or whatever large tree is both concealment and cover. Wait and see what--if anything--the idiots do next. Wait a bit more.
Nothing? Probably just a momentary stupid; continue toward home, but with increased alertness.
They come driving back? You're concealed. Stay that way.
They come back and exit the vehicle? Whole different deal. First off, stay concealed and watch. They may give up and leave, which is what I would expect. If not, well, you're alert and prepared for whatever next arises and you may well have a reasonable and prudent person's need to use deadly force.
Never let your ego drive your behavior.
