After the Route is selected Waze can display "Reports Ahead" or they pop-up on your journey, Each report is given a distance, type and location. e.g 81.8 miles / Heavy Traffic / Flore.
Unfortunately I have no idea where "Flores" is. So it is difficult to relate to where in my journey this delay is.
What would be much better would be to use the Road and Junction numbers ( US: Intersection numbers).
The locations are often small towns i have never heard of.
E.g. If it showed " 81.8 miles / Heavy Traffic / M1 J14-J15 near Flore" that would be a lot more helpful as I know the M1 motorway and where these junctions are in relation to my exit and destination.
