Currently, when there is traffic congestion ahead, Waze does not clearly change the road color on the map. Sometimes it only shows thin orange borders, which is not enough for the driver to quickly recognize the slowdown.

It would be much more effective if, whenever there is congestion or slow traffic, the road itself changed color (instead of remaining purple). This would make it easier for drivers to anticipate and react to traffic conditions without relying only on borders or icons.
