There should be an option where you can see bike lanes, it can pop up on the side of roads that actually have bike lanes. If there is a bike lane and you need to turn where the bike lane is, it could give you a warning to watch for cyclists in the bike lane. With adding bike lanes, you can even add a feature for cyclists! When you put in your destination on Waze, there could be a pop up that is a little button which says CAR or BIKE. You could switch it on or off depending if you are a bike or car. This would help expand waze and would gather some new members. I am a cyclist myself and this would be really helpful. To add bike lanes, you could go in WME (Waze Map Editor), click the + button, click road, then it could be under walking trails or a new category it self.
