I am in general fine in traffic (though I can't stand driving a car) and don't really run into things but I am sometimes so oblivious to details of my surroundings. For example it took me months to notice that the wall directly behind my oven is made up of tiles of all sorts of colours. Or that the lampshade above the eating table is pink. Or that directly above our letter box is a big red "No smoking" sign. Also I generally notice when something has changed on my street but I couldn't tell you what used to be there before.
