Ice on road and water on road reports are critical and would increase adoption in the US mid-west where its lacking. If only one option could be provided and I had to pick - I would pick ice!

I also second the Ice on road and flooded road options - this winter I have had many occasions to report those and have had to instead use Snow or Rain respectively then add a description or comment (not very safe)

I was shocked to find that there was no way to report ice on the road. This is far and away one of the most hazardous driving conditions. Right now, the only way to communicate that to other drivers is "Hazard -> On Road -> Object on Road, and then TYPE (oh, yeah, THAT's safe to do in icy conditions) "Ice on the road". This is a huge oversight, Waze. Please, fix it.

Hazard -> On Road -> Rubberneckers

Please add DISABLED VEHICLE to the "In Lane" reporting option. This is especially important when traveling at high speeds on freeways. As much as I don't want to run over already dead ROADKILL or flatten some other OBJECT, it's far more important to avoid slamming into a stalled car at 65 mph.

For towing a trailer, driving an RV or just a taller vehicle it would be nice to add a "High Winds" hazard option. Many times I can wait it out or change my route accordingly.

Road closed: Also, this could be set as reported or unreported in case it is a personal need or preference.

Road closed is very important. If the only other route is a long distance then choosing routes will not select another viable route.

For the road closed. It would be useful to be able to mark the closed roads on the map in order to avoid them, also, to have the ability to program the time period when these roads won't be available. I believe it's easy to achieve with the map editor.

The rest of the users could receive a notification of the blocked track, so they can accept and even vote for the notification, so they can avoid the route and skip false warnings.

Bump alerts would be very helpful!

Hazard -> On Road -> Pot Hole (should remain on map until someone else updates saying its not there)

Hazard -> Shoulder -> Heavy Vehicle Stopped

Add: Hazard>On road>Car on road

It would be great if you could also add the new speed traps we have in france called "Radar Tronçon". These speed traps compare the speed average between 2 points.

1st Cam (register the car and the time) -----> a few kilometers -----> 2nd Cam (Register the time)
A computer compare the average speed calculated with the 2 registered cam with the speed limit.

It would better to use images instead of using a text list.

My wife also commented that "WATCH OUT" especially when you are over a quarter of a mile (or .4 Km) from something is a bit much. She suggests a calmer "Caution" warning.

And while on terminology, "My lane/Other Lane" is not as obvious, when travelling on a 7 lane Highway. Perhaps changing "Lane" for "Side" would be more appropriate.

Also ability to add different road signs using map editor would be really neat. So Wazers could also map road-signs where they are located. This is good option but will take a lot of effort on your part, as different countries have different road-signs. This is what I mean: http://www.gross.lv/lv/theory-topic.html?topic=31

Hazard -> Weather -> Solar Glare

I suggest some new reports!
