With the continuous development and innovation of technology, driving recorders have become one of the essential equipment for modern transportation. It has functions such as recording vehicle trajectories, saving traffic accident evidence, and monitoring driving behavior. However, many people may have the question: why don't cars have their own dash cam? This article explores this issue from the perspectives of automobile manufacturers, laws and regulations, and market demand.

Firstly, for car manufacturers, cost and benefit considerations need to be taken into account when bringing their own dash cam. The current driving recorder mainly focuses on safety and certification issues, but for car manufacturers, in addition to these two aspects, they also need to consider operating expenses such as car research and development costs, car market competitiveness, brand image, etc., such as production costs, assembly, and after-sales service. In this situation, it is likely that a large amount of resources will need to be invested in the research and development, testing, and installation of the built-in dash cam, which will affect the operation, profits, and customer needs of the automaker.

Secondly, the law does not mandate that automobile production enterprises must carry a driving recorder. Although some regions and countries have regulations on the use of tachographs, they do not require car manufacturers to carry them. On the contrary, airbags, seat belts, etc. are considered mandatory in some countries. So, for car manufacturers, they need to manufacture cars according to specified requirements, rather than just meeting them.

Finally, market demand is also an important factor affecting whether car companies should bring their own driving recorders. There are already many manufacturers in the market that offer various types of dash cams, so car manufacturers can also freely choose to use them without the need to install them in their own cars. In addition, with the increasing demands of consumers for vehicle driving safety and evidence collection, the demand for dash cam products in the post market field is also increasing. In this way, startups and small manufacturers also have the opportunity to enter the market.

In summary, the reasons why cars are not equipped with a dash cam include factors such as cost, legal regulations, and market demand. However, for consumers, it is still necessary to invest an appropriate amount of money to purchase and install a dash cam when using the vehicle, in order to ensure safety and reduce the difficulty of accidents.
