The majority of all police cars, fire trucks, ambulances, city buses, etc., already use dashcams. Increasingly, individuals concerned with false liability claims and protecting themselves in the case of an accident are utilizing the protection offered by on-board video recorders. This includes every day drivers like you, parents, truckers and 18-wheeler drivers, etc.
Fleet owners and contract drivers as well can benefit greatly from having a video (and position) data from their fleet vehicles when they are out in service for the day.
Almost every driver should be using a dashcam! More and more drivers every day agree with this statement and join the group of those who are "protected by dashcam".
