Several states have DMV digital alert signs - it would be great to be able to add those warnings to Waze. Example the DMV sign alerts 'accident on 85 South 5 miles ahead all lanes closed' - If a Wazer could input that info by means other than map chats people usually don't read, or at the wrong mile marker it'd be extremely valuable for people traveling in large cities.
I'd pay money to know that in advance!
