Allow the driver to optionally link one or more Bluetooth devices to his/her profile. Then, when somebody (1) gets in the car and then (2) puts the vehicle into forward/reverse, if the bluetooth device(s) is/are not detected it can pop up an alert to remind you that you might have forgotten them. Additionally, if the device is connected but then disconnects when you get say 100m from your starting location then it can alert you (in my case I think my phone will link up from inside my house, but not once I pull away).
