I second the request for 'Vehicle Stopped on Roadway'. I see it all of the time.
Additionally, I would like the audible warnings to be more specific, so I do not have to look at the screen. At the very least, the audible warning should distinguish between a hazard on the shoulder and a hazard on the roadway.
This may just be my old age, but it looks like the text size in the pop-up warnings in the latest version or two got smaller so it is nearly impossible to read quickly.
Lastly, the Waze icon has never displayed properly in the pull down notification menu on my ancient (3 year old) first gen Droid X, which has a white background.
Otherwise a great app. I use it just about everyday.
