I think a huge part of the current problem is technology - in days gone by car thieves would be breaking into cars and hot wiring them, then later on the norm breaking into homes or fishing letterboxes for the keys.
Nowadays it’s lucky dip with high end cars and keyless entry, thieves have almost zero chance of getting caught. It’s a lot easier to steal cars and much harder to catch people doing it.
Unless you are awake every night between midnight and 5am or have 24/7 security (most people don’t and thieves will always find somewhere that doesn’t) how would you ever know?
No car alarm sounding, no broken glass, no banging, no breaking into houses. Just a car vanishing off a driveway or the roadside in the dark of night. And if they’re unsuccessful, they leave without a trace.
The Police have to shoulder some responsibility, but the game has moved on.
I had an attempt about four years ago now, which was unsuccessful and I caught a gang in the act. What I found frustrating was that it wouldn’t have been impossible to have tracked the thieves, potentially interrupting their operation but the police took little interest in this and never followed anything up.
Prevention is key, take reasonable precautions and avoid becoming another statistic.
