Google adds Waze feature to iOS and Android version of Maps
Clicking on the traffic overlay will show accidents and other incidents that affect traffic which can turn your commute into a bumper-to-bumper grind. Keep in mind that these reports are sent in by Waze users who happened to take the same route you are now traveling on. And the beauty of the whole thing is that Google Maps will create a route to avoid known incidents and if an accident happens while your on the road, it will re-route you as well.
