It would be great to have a new category of permanent hazards for dips in the roadway. Currently, there is no appropriate category for such. Many municipalities have man-made dips to serve as a traffic calming device. On the other hand, natural dips in the roadway may be encountered by Wazers throughout their travel. Having this permanent hazard can warn Wazers of such occurrences ahead of time in order to slow down and prevent potential damage to vehicles.

Another suggestion (https://waze.uservoice.com/forums/59223-waze-suggestion-box/suggestions/38921404-reporting-uneven-road>) regarding uneven roads might be relevant as part of this new permanent hazard category.
