Consider a case where you have a very simple configuration which I
shall try to draw in ASCII:

|
|
|
+---------------x-------------o-----------
|
|
|

Let "o" be the bollard and x your destination. For badness, let's also
assume that there is only a single way segment between o and the
junction at "+".

So now the entire piece of road from junction to x is access=no. Do
you think the restriction will be ignored in this case?

(maybe this won't matter in the real world, I'm just saying it now in
case it could be. I suppose the harder and more correct solution would
be to carve off 5m either side of the bollard into separate restricted
segments)
