The display auto-rotate between landscape and portrait mode is a pain in the ass when you use it on a motorcycle. The trouble is that the screen swaps every time you lean the bike into a corner, or sometimes even when you hit a bump in the road.
I can't see an option to disable the function and lock the screen into always portrait, or always landscape. If it isn't there, is it something that could be added to a future version? I have seen other iPhone apps that allow screen rotation to be locked.
As a car driver, I have to say... please be considerate when driving through traffic jams. Motorbikes can zip in and out of stacks of cars and could falsify a genuine traffic report. Not moaning, just saying be careful
If you lock the iPhone settings, Waze automatically put the gps in portrait mode. But my iPhone is on landscape mode on my motorbike. So I would like to choose the orientation and fix to it in the app.
I don't remember a Waze specific setting, but you can lock the entire iPhone to not rotate while you are riding if that helps. (Bring up task tray, swipe to the iPod controls, hit the orientation lock on the left.)
