In my answer on Tobias unfortunately I followed his mistake, half way.

He had not only commixed a statement with an order, he had also read "to need" as "to use".

Now I tell it more precisely:  
"is not needed on non-motorized thoroughfares" means "on non-motorized thoroughfares it can be described without that tag",
but it does not mean "on non-motorized thoroughfares it must be described without that tag".

Yours', Ulrich
