    If designed ergonomically and used appropriately, In-Vehicle Technologies (IVT) have the potential to significantly enhance safety, mobility and driving comfort. This study focuses on the use and user assessment of common IVT such as cruise control, navigation, speed alert/control, and mobile phone. The data was collected by a standardized web-survey and included 7677 drivers in nine countries. The findings of the study highlight some cross-cultural differences in the use of the systems, especially in the use of a mobile phone while driving. In addition, some differences found between driver groups indicate that some systems are used most by drivers with high annual mileage. The possession and use of cruise control and speed control seem to correlate with driving experience, and also with the characteristics of the car fleet (age, make) in different countries. On the other hand, some systems, especially navigation, are widely used in all driver groups regardless of driving experience or age. This emphasizes the importance of user-centered design and evaluation in real traffic, especially since users reported interacting with the systems (even while driving) on the one hand, and experiencing challenges in understanding how the systems work on the other. The questionnaire study formed part of the INTERACTION project, which now continues with naturalistic driving experiments and in-depth behavior analysis of the selected IVT systems
