Fluid traffic areas
Waze only reports traffic jams. It would be useful to also mention the fluid traffic areas.
Why would waze need to report the fluid traffic areas... there's no need to report the normal situation... maybe an area would be "fluid" as no wazer travelled on it the last few hours e.g. while in fact it's completely blocked.
If you get a report for a traffic jam it's because some wazer reported it, no-one is going to report fluid traffic.
