On some days, Waze suggests some really amazing detours and it saves a lot of GAS, as the vehicle is constantly moving. Also, the route saves you time. At other times, WAZE take you straight into Traffic or to a route, with building up traffic, and then asks "Are you stuck in Traffic". Really !!!. You told me to go there.

There should be a way to give WAZE thumbs up, for saving time. and Thumbs DOWN for suggesting a route with more traffic with no options for detour.

Saying there is traffic ahead , and taking you there, with a pre-warning , "Traffic Ahead", is what all advanced GPS devices do. Waze should be quick in suggesting an alternate detour. Also, have lane suggestions. Routes with minimum Left Turns and Traffic Lights.
