Indicating your turn is a basic road law everywhere in the world. However, many people don't follow this law, completely ignoring it. Since so many people use Waze in their life, it would be crucial if Waze helped its users be more aware of what they are doing. There is already a reminder on the app for you to turn on your headlights when on the highway, and that has proven to help people remember to do so. Doing this will help people drive accordingly to the law and prevent many accidents.
