Actually the said car has a continuous internet connection, using a sim card, so I guess syncing time wouldn't be that difficult. Also I remember some Renault Espace in France which had a dongle but then you had to put it somewhere specifically in the car to start it. Adding an NFC/RFID chip could solve part of the problem maybe... But yes you are right this require maintenance.
