What is a PathfindingModifier and how and can you use it?

Hello there. I was working on my game when I saw in the object inserter that there is an instance called “PathfindingModifier”. I was actually working on a system not too long ago on trying to stop a car to walk over grass and only to drive on the road.

Is it possible to use this and if so how?

I did search the devhub but to no avail

Many thanks

Probably this is unused instance or beta thing, anyways it cant be edited by script or changed somehow.

I dont know how to use it, this is what i think about it

Yeah. You know what you are probably right. I do wish they would finish this soon as this would definitely be of help to me.
