This is a sidewalk grip where it ramps up from the street. I noticed that all of them have the same melt pattern. Low traffic area when no one was out.

Just curious if anyone knows why

    In addition to the possibility of reinforcement bars it could also have to do with the thickness of the tactile pad or it could have recessed spots underneath (to save on material if it was injection molded) that could create an insulating air gap.
