Change blindness

This phenomenon is known as “change blindness” - only a tiny fraction of all the information going into your brain enters your consciousness. People often fail to see a change in their surroundings because their attention is elsewhere.

Even stranger, if you are concentrating on something, you can become blind to other events that you would normally notice. This “inattention blindness” is possibly the reason why motorists collide with cyclists.
