I would prefer to see traffic notifications not respond at all to a stationary vehicle, since most of the time, even in very congested traffic, the vehicle moves a little. A stationary vehicle would normally indicate someone is parked.
If someone is indeed "stopped" in traffic for longer than a couple of minutes, they would presumably have the time and capability to flag this event on their phone manually.
i agree to that
i a total traffic jam you'll have all the time you need to set any message about this. there is no need for an automatic message about standstill. my waze-app created this message several times, standing in front of traffic lights. this is NOT usefull...
