Is the Rear Dash Cam Important?

[McAndres]

Dash cams at the rear are not crucial. In theory, a dash cam only needs to record the driver's primary field of view, and rear-end collisions are generally the fault of the following vehicle. The functions of a dash cam are as follows: 1. Record various driving and driver operation statuses: This includes data such as mileage and speed. Models with GPS modules can also track the vehicle's location and route. Analyzing the collected vehicle and driver operation data helps optimize vehicle performance and correct poor driving habits. 2. Assist in determining traffic accident liability: Dash cams record driving statuses (speed, braking information, turn signals, doors, mileage, location, direction, etc.). By extracting stored data from the dash cam, it can help scientifically determine liability in traffic accidents.
