With specific respect to ADAS systems reducing fatigue: https://www.sciencedirect.com/science/article/abs/pii/S1369847814000904 https://www.sciencedirect.com/science/article/abs/pii/S13698... > We investigated the effects of ACC and HAD on drivers’ workload and situation awareness through a meta-analysis and narrative review of simulator and on-road studies. Based on a total of 32 studies, the unweighted mean self-reported workload was 43.5% for manual driving, 38.6% for ACC driving, and 22.7% for HAD (0% = minimum, 100 = maximum on the NASA Task Load Index or Rating Scale Mental Effort). https://www.sciencedirect.com/science/article/pii/S1361920921001851#b0165 https://www.sciencedirect.com/science/article/pii/S136192092... > Interviewees reported being less mentally and physically tired—though most focused on the former—both while in transit and upon arrival at their destination. Twelve (12) interviewees mentioned this. The reduction in tiredness seems to be because, from the interviewees perspective, partial automation takes over a substantial portion of the driving task.
