No they aren't. Out of curiosity I setup an rtlsdr and connected it via RTL-HAOS to my home assistant server.
The antenna is in the middle of my house and over the last month I have logged over 200 different tire pressure sensor id's

It does have some surfaces that look like they could produce lift.
Traveling fast enough it could probably lose thrust and "land" horizontally... Until the legs grab and it tumbles.
Yeah this is something a well trained neural network would make simple though. So long as you have the processing power, and enough storage.
I'd imagine you'd be able to purchase some identifying information from data brokers and eventually link ids to people or families.
