Make it (much) easier to report a road/street problem (e.g. temporary lane blocked by construction)
During the commute I often encounter a slowdown and would suggest your app does a couple of things:
1. very quick way to report "x of y lanes obstructed"
2. waze should "observe" my route and immediately observe all waze "fleet" and "learn" how we are either getting stuck or how we are skirting around the obstruction
