Not seeing things

[#1]

We often read about people who see things that are not there ie Hallucinations.
But have you ever not seen something that was there ?
In my younger days I worked on a night shift for a short time, one morning returning home from work I could have sworn the road was clear with no traffic about and was just starting to turn right on my motorbike when I was suddenly aware of a car coming down the road, had I been going any faster I would have been under it's front wheels, I was in my early 20's yet this incident has always stuck in my mind as it had such an impact on me.
There is a recognised condition called, Inattentional Blindness' perhaps it comes under that heading so have you ever not seen something that was clearly there ?

I had a very similar experience about 40 years ago after a twelve-hour night shift. Found myself accelerating towards the back of a much slower truck in front. If I hadn't realized I would have been under it. Not sure about Inattentional Blindness, I think it was more like being asleep!

Possibly due to the fact that we all have a 'Blind Spot' in each eye, so if something is coming from the side and is in the blind spot of one eye, whilst the other eye cannot see it due to an obstruction such as your nose (I'm not inferring you've a large one    ) then you won't see it for a short time.
See this Wikipedia page for example.
