When driving on a route, Waze lets you select alternate routes. However, there is not enough information given to make an informed choice.

Examples:
A) Waze may suggest a different freeway than the one you're currently on, but to get to that freeway you may be routed on side streets. You know that the traffic on the side streets is not accurately reported by Waze and are busy at that time of day and so you would avoid that route if you knew Waze would route you that way.

B) Waze senses that traffic is getting worse ahead and suggests a new route. It gives you the major streets (maybe a different freeway), but doesn't give you any real information about the new route. Maybe it's routing you through intersections you know are extremely bad.

As Waze doesn't give you any detailed information about the alternate routes, it's impossible to make informed decisions about these other routes. Allow users to see the complete route for all suggested routes and alternate routes.
