I often see construction zone or potholes noted on the map while driving on a major highway that have NO evidence of either being in place.

However, most of these appear to mark bottlenecks, where traffic often slows down.

I would suggest the addition of a "Bottleneck" category that could more usefully be used for those spots.

I assume those sites have "battling" Wazers, those who Thumbs up and those that Thumbs down. For spots with frequent up vs. down for a site, they could potentially be marked as a bottleneck.
