• Advanced Driver Assistance Systems, including Driver State Monitoring like Drowsiness Detection Warning (DDW) and Driver Health Warning (DHW), are increasingly integrated into vehicles to enhance road safety. However, factors of user acceptance of such assistance remains understudied. This paper presents an exploratory user survey on the acceptance of both warning systems using the Driver Monitoring Acceptability Scale (DMAS) questionnaire. Results show high perceived ease of use but varying general acceptability and concerns, with no significant differences between drowsiness and health warning. Willingness to pay is low, and responses among experienced users are polarized. On a conceptual level we contribute by providing a German translation of a shortened questionnaire as a candidate instrument for future surveys. Our study advances the empirical understanding of drowsiness detection and health warning acceptance, offers insights into DMAS applicability, and outlines future research for improving automotive health system design.
