A: Yes you can, Apples AirTags are set to be connected to a phone right out of the box and once connected, it is link to the Apple ID that the phone is linked to. You can chose to set all 4 up on one iPhone or you may use each of them for different iPhones.
Q: If put one in car will it be traced easily if car were stolen?
A: I’ve got one hidden inside my car for exactly that use in mind. I’ve disconnected the Air Tag speaker (ifixit has a disassembly guide on their site: I removed the magnet that’s glued inside, so it won’t alert a car thief to its presence). My car must pass by another cell phone to update its location, but I live in the city, so that’s no problem. I’ve set it and left it in “lost mode”, since it’ll update its location more frequently (other iPhone users must physically tap on my Air Tag to see a programmed message: it’s impossible they’d do that, since I buried it under the dash). “Easily” is hard to say, but I think of it like my poor man’s GPS auto theft recovery device (although GPS is more accurate, GPS devices require a $40 monthly subscription fee).
Q: How far can this airTag be detected if it is in a car and traveling?
A: AirTags use other iPhones to provide location data. The AirTag's range is unlimited provided that there are iPhones nearby. Within Bluetooth range, Precision Finding will show you precisely where and how far away the AirTag is (on iPhone 11 and 12).
