This is really fascinating from a psychological perspective but horrifying from a general societal perspective. There have been prank videos in which people scare others in a zombie style pretend attack, but anymore I’d just assume they are on flakka and start shooting. I’m not even sure having them bounce off the top of the car would do it. Time to start carrying a trunk .308 to supplement the .45 just in case. Pretty sure that would do the trick.
The “zombie apocalypse” is not a purely fictional scenario.
I’ll bet at least some advanced nations have weaponized chem/bio agents and dispersal systems that can reduce entire cities to zombie killing fields.
I recommend the Lee-Enfield. If you are on a budget, a Mosin-Nagant carbine will do the job.
