Bizarre! The three yellow dots disappeared either singly, in pairs or all together until I moved my eyes. Occasionally, one of the yellow dots became green as well, only to be restored when I moved my eyes.

I don't think you can explain smidsy via stationary eye sleight of hand tricks. I have never seen a motorist that I could believe lost track of me. Its not the thought process I go through when waiting to give way at all - ie I identify the thing that I have to give way to, and wait for it to cross my bows, and don't need to track it to do so. This I believe is normal for most road users.
SMIDSY is more often a euphamism for sorry mate, I couldn't work out that I had to give way to you there, or sorry mate I didn't look at all.
That is an impressive and disturbing optical artifact.
Though I believe the dancing bear is more what is happening. If you aren't looking for a bicycle sized object then you aren't going to see one. I never fail to instantly spot a cyclist when I cross the Canning St bike boulevard (whether I'm in a bike or car), that's because I'm consciously looking for one. The other day I did briefly miss spotting a cyclist as a rapidly approach a roundabout with poor visibility. I did spot the cyclist and I had time to stop and wave at the cyclist. But I was still a little unsettled that I didn't immediately notice the cyclist. I too am not as conditioned for looking for cyclists as a good dutch driver.

I believe this to be true. I doubt anyone would fail to see a big truck and I don't think anyone has ever not seen me in my smallish white sports car which is below average height. But I've been missed/ignored on both bicycles and motorbikes over the years.
The other day I was turning left at a T intersection. Bright sunlight. Flat, straight road. I checked right, nothing coming. Checked left, nothing coming. Checked right again before putting the pedal down and... Holy ....! Where did that come from? Black car... deep shaded background... no contrast ... no lateral movement ... no vertical movement ... you get the idea. If any one of a dozen factors had changed even slightly, the car would have been perceptible.
