96. The expert from OICA introduced ECE/TRANS/WP.29/GRVA/2023/9 as amended by GRVA-16-23/Rev.1, aimed at modifying testing requirements on the final steering amplitude in case of front tyres saturation. The experts from Japan and UK supported the revised document, as it addressed their comments. 97. The experts from Canada and the United States of America inquired if there was enough evidence demonstrating that the modification proposed would not lead to a safety decrease. They asked for more data and documentation to support this proposal. 98. The expert from OICA responded that no negative impact on the safety of vehicles was expected, as shown in previous GRVA sessions, based on evidence. She clarified that the reason for this proposal was the introduction of new steering technologies with low steering ratio. She stated that there was no added value in continuing to increase the steering wheel amplitude during the test after the front tyre saturation. 99. GRVA agreed to resume the discussion at its next session. 96.
