Thank you cytryn as well. Thank you for your suggestion. All areas that are drawn are with tag access=no, which prevents routing through that. However, u send an example where routing is too short, point A and point B are too close, in that case, routing will go through the area sometimes, and on this area specifically, I intentionally put foot=yes tag but will remove it since it can create mistake like that.

area:highway is very familiar to me but is still in an experimental stage and it does not render on the map, once is completely in use and approved I will easily change every area with area:highway.

Thank you ChristinA so much!
