Introduction
Conclusion
Study II
Pre-Study
Introduction
Attitudes
• 20 licensed drivers (14 ♂, 6 ♀)
• Driving experience: >10,000km
• DAS experience: from almost no to high experience
• Method: 4 focus groups
Pre-Study: Focus Groups
Conclusion
Study II
Introduction
Pre-Study
• Participants did not perceive DAS as necessary for themselves but strongly supported that close persons (e.g.: partners, children) should use DAS
– close persons are perceived as being more safe when driving cars equipped with DAS
– the way of imposing the questions to participants influences the way of judging the safety of DAS.

Study II : Questionnaire
• 211 licensed drivers (120 ♂, 91 ♀; average age: 40.010 years; SD = 14.190 years)
• DAS experience: from almost no to high experience
• Method: questionnaireConclusion

Study II : DAS experience
1. Did you - and if yes, when did you first - used the particular system?;
2. How often do you currently drive with the particular system activated? and
3. How familiar do you feel with the particular DAS?

Study II : Attitudes towards DAS1. “Would you wish that closely related persons (parents,
children, partner, friends) use the respective system?” (asked for each system listed in table 1) (answering mode ranging from 1 ‘no, not at all’ to 7 ‘yes, absolutely’)
2. “When a child is a passenger in the car, the respective system should be activated in order to be able to inform, warn or intervene if necessary.” (asked for each system listed in table 1) (answering mode ranging from 1 ‘absolutely not agree’ to 7 ‘absolutely agree’)
3. “The activation of the respective system so that it can inform, warn or intervene if necessary is dangerous.” (asked for each system listed in table 1) (answering mode ranging from 1 ‘absolutely not agree’ to 7 ‘absolutely agree’)

Study II : Results
• One significant correlation was found for the effect of drivers’ level of sensation seeking on attitudes towards a specific DAS. The higher participants scored in ‘sensation seeking’ the safer they judged the Traffic Sign Recognition System, r = 0.135, p = .025.

Introduction
Study II
• in terms of safety, drivers’ evaluate the 29 systems differently
• gender is not a decisive factor influencing if a system is perceived as safe or not
• level of sensation seeking is not a decisive factor influencing if a system is perceived as safe or not
• The availability of DAS and to be able to afford (also advanced) driver assistance systems might contribute to a higher DAS experience in general public and consequently to a more distributed positive view on DAS
