21. The expert from the Republic of Korea introduced GRSG-130-09-Rev.1, proposing the consolidation of similar subfunction controls (e.g. climate control) into a unified system for the purpose of simplifying selection and reducing distraction while driving. Some GRSG experts agreed in principle with the proposed solutions. The expert from the Republic of Korea explained that the proposal clarified the text of the UN Regulation, reduced distraction and relegated non-essential elements to sub functional levels. He announced a concrete proposal for the April session of GRSG. The GRSG Chair invited interested experts to provide feedback to the expert of the Republic of Korea.
