In this paper I address the issue of false alarms as they relate to the development of automotive active safety systems. I argue that false alarms are not only unavoidable; they should be considered an integral part of the design of active safety systems that address potential accident situations. Accidents are rare. Hence the base rate of true alerts will also be rare. This fact has two undesirable consequences if designers strive to eliminate all false alarms. First, the few true alerts would be so rare that the driver’s reaction can not be expected to be efficient. Second, the few issued alerts would be insufficient in number to enable drivers to calibrate trust in the system. I suggest that it is more prudent to acknowledge that there will be false alarms and focus on achieving driver acceptance for the issued alerts. We can take advantage of the drivers’ subjective perception of potential accident situations to guide the specification of the system’s alerting criteria. Such systems are likely to achieve higher driver acceptance.
