It is kinda of annoying, that Waze doesn't auto-stop reporting, or have a "run but don't report" feature. I understand that it might hurt if a lot of people started using it all the time, but for those that bike, are checking the traffic before they get off the train, or even as simple as checking the traffic at home before heading out, it just messes up the traffic for everyone else.
I was checking something on in Waze when I got home, and it alerted me that traffic was at a standstill on my road. My road is only a 1/8 of a mile but since I got home and parked, and there was another Waze user on the map, also (I assume) at home and parked, it reported a traffic of 0 miles an hour... on a road where I can see both ends of the street. I'm assuming when I arrive at my work, or a restaurant or something similar, it's doing the same thing, unless I make a point of telling Waze to turn off. Which, I have to admit being new to the Waze system, is not something that's ingrained into my pattern yet. This means every time I arrive at a destination (some I've told Waze I'm heading to, others i just stop at), it's reporting that the road i'm on has just come to a complete standstill. Not good.
I often use Waze now to check on traffic conditions or just see the different settings (just figured out I can do 3d instead of 2D, hey I've only been using it a week!)... so perhaps I'm missing something, but from this thread it appears that this feature might be a rather large whole in the auto-crowd sourcing nature of the app. If I'm wrong and there's some auto feature built in that I'm missing, I'd like to be told. I've tried to do my research before posting, but hadn't found anything that allows me to activate/use Waze without it reporting back.
