Acceptance of the System in Specific Situations

The acceptance of a preventive system is an important criterion during development. As long as the future driver of a vehicle has the choice to decide whether to have or not to have a system, his acceptance will influence his decision to use or deactivate the system (if possible) or buying it again. As a consequence, acceptance does influence the safety benefit of a system, especially, if the system can be deactivated (in this case due to low acceptance). This section explains the findings on acceptance from the driving simulator study. 

Acceptance is not only limited to undesired system actions, e.g., false positives or false negatives, but also includes desired actions (e.g., correct positives). Two different approaches are used to gather information about the drivers acceptance
