Being gutsy and having right of way are two different things. What's that old adage? Many tombstones could be engraved with "But I had Right of Way"...

I always combine the head turn with an arm signal, and only make the move if I have adequate space relative to the speed of the traffic behind me. I do something safer if the conditions aren't good. The challenge is making it possible in the most intelligent way. I don't trust any driver to understand their "duty to either stop or negotiate a safe passage around me."

If you have established your postion in the lane, and you are signaling your intent, you have right of way in regards to the traffic behind you. You still have to yield to oncoming traffic of course.
