[Tagging] Roads with no speed limits

AFAIK, no maxspeed value means that the default maximum speed for this type of road in this area applies, so I wouldn't add this tag when there is no sign; that would also fulfill the "Map what's on the ground" principle. Beware that, if there that was a maximum speed sign (hundreds of) kilometers before, which is still in effect, you should then use this value; that kind of situation is pretty common, at least here in France, as it prevents installation of redundant signs after each junction.

Here in Phoenix Arizona more than half the freeway off ramps have no listed speed limit. Does (maxspeed=none) work? I've worked hard here in the valley adding speed limits and when you look at the ito map it looks like no one added any to the off ramps when in fact most of them have been surveyed and they have none. How to tag them?
