It is actually pretty bad if someone uses this app as cyclist. And I wondered where all those not-real traffic jams come from...
In current state waze is not to be used by pedestrians or cyclists, because pedestrian/cycling roads can break correct navigation for cars (if drawn all around) and that also is cause for false traffic jams reports.
What do you mean by "on the web map"? If http://world.waze.com/livemap/
- than live map has some glitches in displaying updates. If https://world.waze.com/editor/
- than editor must display all latest additions, even those not yet in the app.
And update frequency is to be seen here http://status.waze.com/
