Simon, could you elaborate on why the local organizers for Birmingham threatened to walk out?

@mlcd Thanks for your comments. The layer is updated daily (with a few exceptions).

@Pierre-Alain Dorange, your examples are pretty obvious. One-way streets either start or end at ways where car traffic is not allowed.

Malenki, this is not an error that get’s visualized in the layer. if you move the markers along then you see that everything is connected, but there is a detour. The problem is not reachability but the detour.

Do you have an example to look at?

Well, yes and no. At the moment our capacity is rather limited. But we may implement that feature in the future.

Thanks!

Areas are not routed through (yet).

It has world-wide coverage. The renderer seems a bit over-whelmed at the moment.
