Can't See The Forest For The Trees (Bottom-Up Thinking)

Looking down a supermarket isle is a natural single point perspective visually speaking and because the shelves are so tightly packed I think it can easily create a visual illusion because it's too much to take in the detail and identify every individual item on the shelves without directly looking at them so it's like the glaze-over effect. You're seeing these things mostly pass you by in your peripheral vision so it's hard to focus on everything in your immediate field of vision, and I believe that creates a kind of shut down effect. Unless what I'm looking for has a very distinct shape or colour not common among other products of its type it is too easy for me to just walk past its place on the shelf in a daze.
The contrast to this is driving, even on the busiest motorway I can keep track of the location and speed of every vehicle in my vision because they are not packed into 100-300 cars per 10 meters.
It's another reason I find the "high functioning" vs "low functioning" labels unhelpful. I can happily drive many miles to get to the supermarket but once there I fall apart, I end up having to get a worker to walk me around to where the stuff on my list is, and I got the feeling a few times that they see me with my car keys and think "but you drove here, how come you can't do this on your own".
Sometimes I think I want supermarkets to be like the olden days where I could just give a worker my list and they'd go get it all for me, and you can do that online now but once it's already in your home is too late to tell someone that the bag of veg that got delivered is already out of date. :/

I find it hard to reconcile how some things are so easy, yet others that should also be simple, just seem too complicated.
