Barrier=spikes?

Hi guys,
you all familiar with a very common one way barrier with have spikes on spring. It let’s you pass only one way, otherwise will punch your wheels.
For example: http://img2.wikia.nocookie.net/__cb20120401082221/drivingworld-htif/images/4/4f/Road_spikes.jpg

How would you map it? barrier=spikes ?
The Barries wiki page gives this image for barries=spikes as example:
Which is clearly not my case.

Thanks.

I think the picture is misleading. The description specifically mentions the use of spikes in payed garages:

I would also suggest adding a “vehicle:oneway=yes” access restriction tag. Together with “barrier=spikes”, the tagging is very clear IMHO.
