Eg the cycleway: in some parts of the world, cycleways implicitly allow pedestrians while in other parts they are implicitly banned. If all mappers just map cycleways and don't care for access restrictions for pedestrians we end up with the same tags meaning different things.</span></div><div><span style="background-color: rgba(255, 255, 255, 0);"><br></span></div><div><span style="background-color: rgba(255, 255, 255, 0);">cheers </span></div><div><span style="background-color: rgba(255, 255, 255, 0);">Martin </span></div></body></html>
