There's always a more cautious option in each of those scenarios. If the self-driving car always errs towards that, hopefully it'll mitigate disaster. Following good driving principles to the letter - accounting for stopping distances etc, like in the Highway Code (UK) - will hopefully allow time for those unpredictable road users. Humans are more risky in that we give ourselves less time to react to begin with.
