I am a driver but still dealing with similer sort of thing but I try to force myself to think different, think If I have been there, have I seen all the angles to the features?
If you see something and think to yourself nope, nothing there, a flag should go up and make you rethink your view, what would it look like if I layed down, if I got on top of something? Moved the other corner of the street? What would stand out if it was in Black and White? Sepia? etc.
I have a habit of something catching my eye, taking a look at it, and overthinking it, and not taking a shot cause I think there is nothing to it.... Hope this helps some.
