Ah, the urge to record everything happening in front of you while you are driving! Dash cams first became popular in Russia, where insurance frauds are rampant. Obviously, people who have been in car accidents while driving before, might need dash cams to record events if they are in an accident again, and want to show they weren't in error. This is just one, albeit main, use of dash cams. Dash cams are also great for recording your travels.
