Others have touched on this, but to try and direct you towards the point of what I said, which was so magnificently missed; this isn't about you or the motorcyclists in that video or whatever fear you think governs my behavior. It's about other people being able to go about their business without the threat of being hit by a motorcycle or body traveling fast enough to end or ruin their lives.
by default its still fear.... the fear of harming others... i didnt say you were afraid to go fast, that would be silly... you can also toss in the fear of crashing, fear of being hurt, fear of damaging your bike, fear of being locked up.... but the primary issue here is the fear of potentially harming others.
and your point was not missed... it's something everyone should already consider when making the choice to ride faster than the posted limit, as im sure everyone in this group has done at one point or another... we each make a choice based upon the current situation, how clear the road is, and what risk we will accept, etc. each time we go fast.
i try to keep mine to what i personally find as an acceptable level of risk... some might be more cautious, and others more extreme.... but its all a sliding scale, you cant judge without being aware of the exact situation at the time... it might very well be a section of road that you yourself might also speed on because it has minimal risk.
