Guidelines 1/2020 on processing personal data in the context of connected vehicles and mobility related applications
Paragraph 1.5.1 Lack of control and information asymmetry
44. Vehicle drivers and passengers may not always be adequately informed about the processing of data taking place in or through a connected vehicle. The information may be given only to the vehicle owner, who may not be the driver, and may also not be provided in a timely fashion. Thus, there is a risk that there are insufficient functionalities or options offered to exercise the control necessary for affected individuals to avail themselves of their data protection and privacy rights. This point is of importance since, during their lifetime, vehicles may belong to more than one owner either because they are sold or because they are being leased rather than purchased. In addition, vehicles are increasingly being shared or rented, not just by companies, but also individuals, and the person whose data is collected may not be able to object to some data processing.
45. Also, communication in the vehicle can be triggered automatically as well as by default, without the individual being aware of it. In the absence of the possibility to effectively control how the vehicle and its connected equipment interact, it is bound to become extraordinarily difficult for the user to control the flow of data. It will be even more difficult to control its subsequent use, and thereby prevent potential function creep.
