Reviewer 2 Report

This paper evaluates ambient in-vehicle lighting in order to take over appropriately during L3 autonomous driving. This research is interesting and useful to consider the way to keep the appropriate driver state for TOR. There are a few unclear points in this paper, therefore I would the authors to answer these:

1. Please indicate the distance and angle from the eye point to the ambient light. Is the ambient light located around the front window? Should it be just above and below the front window, or just to the left and right? If there is a rationable reason, please explain why the ambient light is placed around the front window.

2. I don't think you have explained the transition conditions for the color of ambient light. When and under what conditions do the colors of the green, yellow, orange, and red lights change? Also, do the lights flash continuously or not? If the lights do blink periodically, please specify their frequency, etc.

3. In this paper, only the MW and EEG levels were evaluated, but it would be necessary to also evaluate whether the driver can reliably take over from the automated driver. Have you done this evaluation? Since we are conducting experiments using a driving simulator, I think there should be this evaluation as well.

Reviewer 2 Report

Thank you for the revised paper. The uncertainties I pointed out seem to have been cleared up. However, the reference section of the resubmitted paper seems to be all missing as far as I can ascertain in my environment. If so, the authors need to correct this.
