    Gas station roads on map must be made using parking-lot or service road types. Waze system such type of roads doesn't take in account when computing traffic load. So be easy. If You are at parking or gas station, You automatically are not in traffic. But....only if map editors used right categories of roads. That must be fine in 99.99% of cases.

    Craig C Chen - Hi!
    If properly made, system could take in account most of the records of cars with similar patterns of shaking.
    By the way - shaking it self caused by human and surface are matter of research. If user - companion is keeping device in hands, or device is mounted in elastic mount, bumps on road make shaking with some kind of echo... for example: there is pothole, but after car shake, any object in human hands ir elastic mount makes it shake several times. Couse human body is like water balloon which waves after impulse like move. If human shakes device him self for some reason - pattern of shake will be different. Also if mount of device is stable and hard, then there will not be(almost) any echo like wave patterns of shaking. So taking this in account, program at server could also filter out these artificial shakes, and only then compare number of passes through same section of road in same direction. Of course it could check also patterns from opposite direction, to make more precise surface graph if road is narrow.
    Using such module, waze could also automatically map or show to map editors road-speed-bumps.
    To map by hand just bad condition of road is not possible. Quality changes less or more fast not as just center-lines of roads.
    I may tell You real story. It was 5 years ago. I used TomTom and we did night ride home from quite far town home. So tom tom drew route which indeed was shorter and faster, but no one uses this road to go form that town to our destination and we understand why. It was 90% gravel in very bad condition and very winding. I believe that after shoveling this is smooth rally-like track, but that night it was awful! Thanks God our car was tough enough! So this example shows that other day or month we could take same road without worries and shaking.

    I suggested this feature as well. And there is solution for arguments mentioned above:
    - we are talking about surfaces which will be noticeable by any modern car, where shaking will take place anyway;
    - intelligent approach to this problem is to check and compare several passes over same road segments. If most of passes are not "shaking" at all or shaking too differently, then it means user's generated shaking. But if shake pattern/graph seems similar after (lets say) 5 passes, then this measurement can be trusted and published. So we don't even need several users crossing same segment, but just compare several passes of same user. It could be useful at remote area.

    Idea is vital for sensitive car users or for those who has little kids could be sleeping or just prefer comfortable riding instead of fastest or shorter route. Those users could just use additional check box for "smoothest surface route".

    But this feature also could automatically warn about not just bumpy road, but real pothole dangers without bothering users to warn. This also could work only after repetitive, same-place expression.

    In addition I can tell that several cities in USA and UK are using phones and community to map bad condition roads. So why not use such feature in whole world through using Waze, esp when worse roads happen to be in less wealthy countries.
