Ghost driver alert
A new alert would be interesting to have to alert drivers on a specific route that a ghost driver is coming their way and that they should be cautious, maybe telling them to stay in a lane and to reduce their speed.

Would it be usefull to implement a Ghost rider alert?
At the moment a Wazer detects a ghost rider, (s)he could send out the alert. Waze engines could calculate the path(s) the ghost rider will drive and alert all (approaching) users in the wider area.
Ghost rider alerts from official instances can also be included...
The alert will disappear when other Wazers do not confirm the alert.
Pitfall: abuse
