I like the 2 AirTag method:
Place one AirTag in a rather obvious spot like the glovebox or center console to act as the sacrificial decoy. This one will likely be found and disposed of quickly if trackers are being watched for by the thief, and hopefully give them a false sense of security for a little bit that they've gotten rid of your vehicle's tracker.
For the second AirTag, disable the speaker (howto video for
Gen 2, and same for
Gen 1) and bury it deeper inside the vehicle, preferably someplace difficult to access. Without a speaker to audibly locate it, it's going to take longer to find and dispose of and hopefully give you more time to track your stolen vehicle.
