TBH your response makes me realize there's possibly a decent use case for bicycles with the right diameter tubing.
> You can try a less reputable mechanic, but they're gonna be pissed when the cops come knocking asking about the stolen car sitting over there and you might not be going back there any time soon. So if you can't find and remove the air tag relatively quickly, what options do you have left? Probably makes more sense to abandon the vehicle and try another one with a lower risk of winding up in jail.
Depends on the skill of the chop-shop or it's folks and where you are.
A fun thought experience would be how much suspicion a flatbed tow truck with some form of faraday cage around the car, below a cover would get from LE.
Agree with your general 'deterrent' concept, I think the main challenge a lot of folks run into is getting lazy with placement. Glove/console boxes, the 'pockets' on the back of front seats, are all stupid easy. Technically anything in the interior, probably can be 'found' with sufficient detection capability.
No, you put that thing somewhere weird and ideally a PITA to get at.
This honestly gives me the idea of finding the right spot in my WRX front headlights to make it not visible; If the spot I'm thinking of will work, they'd literally have to pull off the front bumper to even get at it...
