According to a survey, carried out between December 2019 and February 2020 by Which magazine?, On a panel of 14,000 people who have sold their car recently, 80 % of them did not worry about leaving their personal data accessible intheir old vehicle.

More than half of the users have recognized having associated their smartphone with infotainment equipment integrated into their old vehicle.They then leave behind their complete telephone directory, call history, home access codes of the home or even SMS sent and received.

At a time when data protection is a primary subject, letting your own information spinning as easily is a surprising fact, and yet understandable: once the phone is synchronized on the vehicle, we no longer pay attention to transfers ofdaily information between the two, and many users even go so far as to forget this synchronization.
