If I understand the OP's explanation, this isn't a case of "would you roll a stop sign".


The cyclist in question here put himself in danger and behaved as if it was someone else's job to keep him safe.


That's really different than your example of the right-turn lane in my opinion. I'll take the lane specifically so the slow moving vehicle behind me will see me and not pass me during the turn. All that vehicle has to do is follow traffic laws, and no one gets injured (and I'm not bothered at all by the 2-3 second delay I may have created for the driver). That's a big difference from a fast-moving cyclist assuming that the driver of a pickup was going to waive right-of-way at a 4-way stop.
