Show factors that impact route prediction.
Example: New Orleans has many closures during Mardi Gras season.
I had Waze show route to a Burger King that I knew would be impacted by closures. The pre-route screen did not show any information that would hint to the problem.
The route did come up as expected that was far from a direct route.
Then checking the map in Waze, it did show the many closures that the route page did not.

Waze should show closures, traffic, Hazzard Reports and anything else that would impact the route.
