Japan does not support due to concern that trailer might drive itself.
Germany cannot support in same line as Japan. Wording and definitions could be problematic in related to automation. Want to consider, including work being done on DCAS.
OICA: thought para. 1.2.6. was clear on propulsion. Will come back in January.
Rev.2 resolved the concerns enough to enable recommendation of the proposal to WP.29 for its March session subject to a final review in January GRVA.
