My car has a heads-up display that will show an icon representing the next action in he turn-by-turn directions. One of the key ways this breaks when using Waze compared to Google Maps is when the turn is a roundabout. Waze's roundabout icon is a little vortex with a number in that tells you which # turn (counterclockwise) you need to take to follow the route, and it appears that it only outputs that information as metadata to Android Auto or the vehicle to be interpreted by systems like HUD. This results in my HUD always showing a hairpin right turn out of the roundabout, rather than one that reflects the route, and means I can't temporarily switch off the nav screen to adjust Spotify (for example) if there are roundabouts ahead and rely on my HUD.

This issue is not happening with Google Maps because Google Maps outputs metadata for the exit angle of the turn for roundabouts, so a 90° value would show a right turn, 180° would be a through-path, 270° a left turn, and so on. This exit angle data is what my Mercedes HUD uses to draw the roundabout icon.

I would love to be using Waze instead of Maps, but unfortunately every time I see this behavior it really bugs me.
