It's the polygonal ones that don't go anywhere.  A simple centerline tagged

I do this, too, partly because it handles the edge case of how do you enter
the property on extremely small and ambiguous lots (my mother's place has
more frontage on the street facing her back fence than the street the
address is on) and extremely large lots (the bane of my last job, where the
house I was trying to get to might not even be in the same section

the start of the driveway if the section line
<https://en.wikipedia.org/wiki/Section_line> doesn't have a road on it or
