I have a theory and brought up stats I believe points to it, thats all. I know the UK took on a serious problem with autotheft when car buyers and insurers moaned about it - it was epidemic.
As early as 1992, I saw factory security keypads in cars, immobilizers, chipped keys etc. This was lightyears ahead of anything in the US at the time. And it clearly worked.
My rationale is if there are roughly 1.5 million cars lifted every year and they say 30% are exported (meaning good shit, not some 90 Civic) then that is 450,000 pretty new cars that have to be bought with insurance on someone elses dime.
Yours and mine.
I never claimed this was fact but we can keep debating my non-existent decals or whatever irrelevant babble 
instead of figuring out why car theft isn’t being addressed here.
