People regularly confuse "security through obscurity" with "obscuring your security". The first is bad, the second is powerful. Even before I read about the hacksaw (long ago) I knew clubs by themselves were bad cause they were visible. They reveal intel to the attacker. Intel the attacker can take and, in safe environment, at their leisure, devise way to defeat it. If the attacker doesn't know what countermeasures there are, (or are common) they can't defeat them. GPS trackers can be hidden, but car thieves know about them so they can counter (say by getting car into faraday cage ASAP, or using radio wave detector to track it down and disable. So, you have to be more creative, unusual. Where the club could be useful is a honey pot. Put it on the worthless (to you) car you want stolen so the more valuable (to you) car is skipped over. Maybe bait car has secondary devices for tracking that thieves will be less likely to look for since it had the club and and multiple defenses are unexpected.
