Vision is not 100% reliable.

You have a blind spot at all times. Do you notice it? No, because the brain fills it in with what it expects should be there.

Lots of articles about the brains use of prediction to save energy, here's a random one: https://www.quantamagazine.org/to-be-energy-efficient-brains-predict-their-perceptions-20211115/

Watch some lectures on YouTube to really blow your mind. You need to understand you don't actually 'see' anything, ever. At all times you are viewing your brains reconstruction of its perception of the photons it collects. Yes, effectively the brain contains a graphics card ridiculously more sophisticated than anything we can create.

As for crossing the road, the goal is to keep you alive. You are far more likely to see something that isn't there than not see something that is there.

As others have said eye witness testimony is considered extremely unreliable in court. Our visual system takes up the largest area of our brain and uses a significant amount of energy. To save energy, the brain assumes a lot of things. If you were subconsciously expecting your cat to be inside, at a glance, it's entirely possible your brain put the cat there.

I'm not ruling it out, I think this is a simulation. But if there was a glitch, isn't it more likely the cat would be floating upside down or halfway through a wall or something? Given what we know about the brain it's far more likely to be an artifact of our brains energy saving feature.
