56. GRSG noted that WP.29 at its 192nd session (ECE/TRANS/WP.29/1177, paragraph 121) had fostered collaboration between WP.1 and WP.29 on automated vehicles, and recommended that its subsidiary bodies consider GRSG-127-31 during their next sessions. The expert from OICA underlined the contribution of Informal Group of Experts on Automated Driving (IGEAD), which focused on the user and legal aspects of automated driving. He added that communication between WP.29 and WP.1 would improve not only via United Nations entities but also at the national level. Therefore, he suggested that delegations of the same country participating in both groups should coordinate their position consistently. GRSG finally agreed to provide feedback on the document to WP.29 at its June 2024 session based on the suggestion of the expert from OICA.
