I have a few comments about WAZE after using it for some time..
Allow users to set the side the SPEED LIMIT circle appears on...in Australia as in many other countries we drive on the left and sit on the right seat...on Waze, the Large circle with the speed limit is on the far left and designed for cars where u sit on the left side...needs a switch to allow option side that the speed limit appears on...too dangerous and far away to look at it.
Suggestion 2 - THis is a big one...Alert warnings...Where police, speed cameras, construction is reported ahead, it doesnt warn u far in advance...speed cameras i think is a max of 500m. If there i trouble ahead, some sort of advance warning headers up the top of the screen would be VERY VERY useful. I drive long distances a lot, and this is a big missing feature in Waze. i want to know WHAT's ahead of me, even if its 5km ahead...
Your second suggestion already exists though.
Once you've set your destination and route, you can hit the top bar (where the instructions are) that will come down and show all the list of instructions on your route (under "next turns") but there is also a tab with all the "Reports ahead" that are going to be on your route.
Obviously, the reports are ephemeral, so they can change during your drive.
