So you think you can see it all

Interesting.... on the first example (rotating grid and stationary spots), the spots don't disappear provided that you blink regularly!

Excellent site!

There are a few reasons why bikes get missed,

one of them is they are less common so car drivers don't look for them,

another is about the way the brain perceives things, when some one is driving the brain is processing a hell of a lot of images, the assumption becomes that all objects are cars, as they are the most common, so trucks appear to be closer and bikes being smaller must be further away it happens that car drivers "don't see" the bike because the perspective that gets worked out puts it far enough away that it is safe to turn or whatever, this is what you are thinking about with the optical illusion idea, the eyse see things well enough, it is the way the brain interprets that info that is part of the problem combined with a bias towards cars

Hopefully you get my meaning in this

I don't dispute your rationale on this, but the optical illusion that I provided was a different kettle of fish than you have described. The yellow spots dissapeared at random and at times all together and then reappered. You have described the inability of retinal defination of size and distance.

Now I'm the first to admit the illusional effect in no way comes close to anything that we experiance as bikers or for that matter those that drive. But what it did show was the inability of the eye to gather up images in a constant manner. That's the scary bit, what we don't see and not realise it.

Thats the case with all those image optical illusions I think (could be wrong but the only time they work with me is if I stare like crazy and don't blink)

The eyes are picking up the yellow dots constantly - it's the brain that deems them unecessary due to the fact that they are not moving. This blindnes only happens if you fixate on one spot. Under normal use your eyes dart about all over the place because you can only focus on one fraction of a precentage of your field of vision - really - the whole world might seem to be in focus but in reality it's just a tiny part.

I've had lots of this explained to me by optometrists coz they have fun testing my eyesight - my eyesight is weird....but wonderful...I can't pass the formal eyesight test for a vehicle but optometrists have no hesitation in handing out a form to say I'm fit to drive.

Cobras have the same problem to a greater extent - if it ain't moving/it don't matter.

I am also really interested in these illusions and stuff...
