Admittedly I have no motorways in the area I map, but I have added lots of maxspeed tags recently to try and eliminate (or reduce the number of) mapdust/skobbler missing speed limit bugs. I have a few lanes that I still need to re-visit to confirm whether they are actually national speed limit (theoretical maxspeed - many are clearly not that in practice) but almost all highway ways in Tendring now have speeds linked to them. I am not too fussed what system we come up with, as it should be easy for me to update any ways that need retagging based on the combination of maxspeed, source:maxspeed and maxspeed:type that have ended up on various ways (one was one I just was using to help me know which ways were dual carriageway or not, and the other was something chriscf introduced). I do use the current car maxspeed when tagging national speed limits as the wiki suggested that maxspeed should be numeric with optional units, and I am not aware of any class of vehicles that have a higher MAXspeed than cars (any vehicle with a lower maxspeed will know not to exceed that anyway, surely?).
