People who get carjacked often enough to have an informed opinion about countermeasures don't exist in real life. Instead, refugees exist, and people trying to make first-principles opinions about carjacking-in-theory exist.
I've read this comment many times and still don't understand your point, there's no experts in kidnapping countermeasures? first hand experience doesn't count? kidnappings are not real? something about refugees for whatever reason?
I think you should sit this one out since you clearly don't know what you're talking about
