This is my usual routine.

Sure. It's the head unit (iDrive) in your car.
There is an "automatic lock" security function.
Here it is on Bimmercode (I chose the new 5 Series for your convenience, see the "Doors/Windows" chapter):
https://bimmercode.app/cars/g30/. I am very confident I have it configurable from the iDrive as well.
Actually, it's total bullshit how the gas lid is locked/unlocked!
Having it unlocked when the engine is running or the driver's door is unlocked allows to break the refuelling safety rule and makes it a PITA to refuse refuelling assistance (the worker gets to the lid before I jump out of the car to stop him). Also, having the driver's door unlocked while the driver is out compromises security: even though the fob shouldn't start the engine from the fuel lid, if you rush to get a sucker out you'll close the distance...

You should avoid doing it from a distance, close to the car only. Actually there are complicated technologies used to prevent the old "signal stealing" trick from working, AFAIK.

The fob is always in use to start the engine and to unlock the car if the "comfort access" feature is present/enabled. This is the price of not using the fob "actually" (by pressing buttons or inserting it into the slot).
But they need to connect the fob and the car by relaying, it's pointless to record one party only: a complicated(?) dialog should happen to trigger a function. And by the way, I would guess it's the car that actively pins the fob sending an initial signal, but the fob is ready to receive/reply (and only emits actively on it's own when you press a button on it).
