To really kill the illusion, imagine a long line of people, doing "The Wave". The wave can move arbitrarily fast as the delay between people decreases, and even infine speed! (everyone does their part at the same time, assuming they have synced clocks and aren't dependent on their neighbor for the trigger, which is the key feature of the faster-than-light illusion.)

That's also a good one! ..Basically a sub-example of "phase velocity" mentioned in the greatgrandparent. Imagining oneself as an active participant in The Wave seems like it would boost saliency a lot. I'll try that one next time. :)
