Inserting the fob into the dash positions the RFID in the remote so it can be read by the computer. The computer then knows you are allowed to start the vehicle.
With comfort access you do not need to insert the remote in the dash. The computer communicates with the remote by radio to determine if you can start the vehicle.
Your friends car had remote start. This is not an option on any newer BMW using RFID keys. The car needs to read the RFID in the key before it can start.
The RFID stops people from cracking the ignition and using a screwdriver to start the car.
