Someone else here suggested flagging dangerous intersections; I also suggest allowing us to flag ones that are difficult to navigate in times of high traffic, and including a setting to include these in the algorithm for calculating routes. There's one of these near my house: a left turn where there is no stop light, and a hill to the left over which cars come at full speed. Coming home from that direction is safe, but Waze also wants me to leave home that way, and I refuse to go that way. Would be nice if Waze would "understand" why that shouldn't be considered a good route.
