The Bird (scooter) iPhone app asked me for Bluetooth. It said something about "nearby scooters" which I think is a flat out lie because you unlock them via QR code? Probably also tracking...
There is the completely valid use case of a scooter that isn’t able to send it’s location to the app yet is close by to you. So it can be found with Bluetooth.
That isn’t to say that the app is isn’t tracking where you go, it doesn’t need the Bluetooth connection to its scooters because you need to turn GPS on to find the scooters.
Actually, I have an android phone around here somewhere loaded up with a BLE inspector app, gonna see if they actually broadcast bluetooth :-p
(I'm assuming that most phones have better reception than the cheap cellular modems inside scooters)
