Note: NL opposes--UN R13-H gives 0.7 m/s₂ threshold and specifically wanted to avoid brake lamp illumination just from slowing by engine retardation. UK agrees that proposal should use R13-H specifications. Canada concurs, adding that frequent lamp activation would dilute significance of stop lamp. Frost adds concerns from regen braking discussion earlier in the week. Decision took into account interest in harvesting kinetic energy, but specifically looked at relation with service brake such that cat A and cat B regen braking systems. Recommends aligning with R13-H provisions. Regen used for energy purposes should only send brake signal at high deceleration to avoid confusion with engine braking.
