Speedlimit is not like a missing name - Speed kills and we need to be pretty shure its accurate - Better no speed information at all than a sever broken one. I dont care if the name is missing but i care whether the speed is correct. I'd want my navi to either show me the correct speed or that it doesnt know instead of showing me wrong information 30% of the time. > > Id rather check all the individiual streets and tag them > > one by one when i am shure i have the correct fact. > > And if JOSM could understand the speed-polygon and told you: > "This road has speed limit 50 km/h because of way 2387567." > Would it be a suitable solution?

There is no solution other than local survey - everything else is guessing - and IMHO openstreetmap is a collection of facts not guesses. So better have no fact than wrong guesses - at least thats true for maxspeed. I know its frustrating to see the map grow slowly but better than having a pile of bullshit nobody cares to look after. My experience is that once a street is in OSM nobody cares whether the name, maxspeed or something is correct. So better you be accurate right from the beginning. > Lastly I must say that I really do feel for a perfect, detailed map. > But I try not to forget about other people, especially newbies and also > about those people, who do not spend hours studying wiki. No worry - just ignore maxspeed for the moment - its not that important.
