I use Waze everytime I travel. It's a great app and very user friendly. However when it sends you on a detour (ex: because of construction or an accident ahead), it should say why it's changed (why your taking a detour) your original path. I was traveling by myself over night and didn't take the detour, because I was uncomfortable and unfamiliar with the detour it suggested) to take and got stuck in a construction traffic jam.
