Reviewer 1 Report
Comments and Suggestions for AuthorsThe paper reviews some key metrics of HUD, investigates the structure of various PGUs, and focuses on the development status of AR-HUD, analyzes the advantages and disadvantages of existing technologies. The paper mentions that PGUs uses TFT-LCD, DLP, or LCOS to generate images, but there is currently another technology that uses Micro-LED to generate images, which is also a hot research topic. Therefore, it is recommended that the author supplement some information on the current development status of Micro LED as PGUs, as well as their prospects for future HUD applications.

Reviewer 2 Report
Comments and Suggestions for AuthorsThis article has been carefully written, and I believe it is worth publishing.
However, it is worth mentioning in this work that, sometimes, the augmented reality graphics may direct the driver's attention away from critical road elements.
