Except if the first scenario is solvable (fairly trivially) then why should I assume there must exist an unsolvable scenario?
An argument from the vaguery of "humans have context" with regards to driving is a poor one - humans that are driving do not do a good job of analysing context because of reaction times, and do not share a common context they react to similarly.
You haven't made a compelling case, because you've yet to present a compelling example (i.e. one definitely unsolvable by reasonably usable technology on an autonomous platform). The manhole scenario is based on assumption about the operation of LIDAR which simply aren't true and you've had to modify it in a number of ways to try and make it tricky (i.e. when has there ever been a manhole completely full of water?)
I think you're still confused. The point isn't that any of these scenarios don't have solutions. It's that there is a practically infinite number of scenarios like them and it's impossible to plan for each and every one of them.
