This is absolutely *false*.
the DRC perfectly takes in account the *clearance of each obstacle*.

You can also easily show *each clearance* in Preferences.
Each item can be displayed with its own clearance.

But for high density board, usually only the clearance to the current
track segment being edited is shown.

Also not perfect, it is a very good help, and yes, this feature should
be considered in GAL mode.

This is an help, just like air wires.

The P&S handles such collisions, but in order to
