[Tagging] barrier enforcing maxwidth

[Carl von Einem]

Ok, I misread "The other direction." I read it as "the width enforcement 
on the other side of the bridge" (since two images were linked) and 
there I see bollards on both sides of the road to prevent lorries to use 
the wrong lane...

A chicane or pinch point is not a bollard either - a bollard is meant to completely block access by being in the way. This is a set of "bollards" positioned to do a different job as a set (like the ones used to make a traffic calming=chicane or a pinch) - so i feel that a guardrail or bollard would not reflect the item properly in the database nor be rendered properly either.
