Proposal to revise explanation of Annex 3 in the draft guidance document. The change proposes language clarifying that performance issues constitute an unreasonable risk to safety only when deviations, degradations, or limitations in ADS capabilities, based on analysis of their frequency and severity, present an unreasonable risk within the declared ODD. The revision specifies that listed factors are examples for consideration in determining whether an unreasonable risk exists but do not necessarily constitute such a risk themselves.
