23. The expert of GTB tabled a proposal which allowed for projection of driver assistance symbols on the road ahead of the vehicle, as part of the adaptive driving beam (ADB). This proposal was submitted in a package with an amendment to UN Regulation No. 149 (ECE/TRANS/WP.29/GRE/2020/4 and GRE-83-30). The expert from OICA presented supporting material for the proposal (GRE-83-33 and GRE-83-34), while the experts from Japan expressed concerns identified in the course of their own study (GRE-83-49). Other experts also expressed various views and concerns, such as the need for possible restrictions and standardization of the projected symbols, and that distraction must be avoided. Based on the comments received and pending further studies on the issue, GRE requested GTB to submit a revised document to the next session and invited all interested parties to contribute. Meanwhile, GRE asked the expert from Finland to liaise with the Working Party on General Safety Provisions (GRSG) which had established a Task Force on Field of Vision Assistant.
