There is currently a viral video where some malicious actors overtook a vehicle on Belt Parkway (New York, USA) and suddenly hit the brakes in hopes that the vehicle they overtook would crash into them. Luckily, the innocent driver braked in time and when the crash didn’t happen, the malicious driver reversed and crashed into the innocent road user in hopes of laying claim to some sort of damage (insurance fraud). However, the plan failed for the malicious driver because the innocent road user had a dash cam and caught everything on camera.

7. Test the Setup

Before hitting the road, test your dash cam:

• Check video quality to ensure clarity.
• Confirm that collision detection and GPS features are working correctly.
• Test the power connection to avoid unexpected battery drain.

8. Hit the Road

Once everything is set up, you’re ready to use your new dash cam. Always ensure:
