I've noticed pretty much the exact same thing on this road: https://www.waze.com/editor/?env=row&lo ... =123198852

Always assumed the same thing about a cyclist/tractor.

I think it must be due to someone traveling slower than Waze expects - cyclist or tractor sounds plausible.

However, Waze has no direct information about the nature of a road (or it's speed limit). It builds up history for each road that Wazers travel with the app running, and thus an idea of the normal speed for the road. "Slow" traffic gets flagged when it is slower than Waze expects, so 50mph would flag a traffic jam on some motorways, whereas of course on many other roads 50mph would be fast.

What I am getting round to saying is that there must be more than just the cyclist/tractor using your road, otherwise Waze would take their speed as normal. Also I don't think Waze should be able to flag slow traffic on a regular basis, since it would then become normal and therefore not "slow".

Maybe Timbones would like to monitor it, it's not like he has anything else to do

Previously, one would rename the segment "do not use Waze if cycling" for a week or two, but I suspect that that is frowned upon these days.
