Rearview mirrors do increase the driver's field of vision, but streaming rearview mirrors have transmission delays, which can easily lead to accidents. Streaming rearview mirrors: As the name suggests, "streaming rearview mirrors" refer to rearview mirrors with streaming media functionality (simultaneous transmission and playback). From an academic perspective, they are rearview mirrors that can play (view) real-time video footage being uploaded from the rear camera. Disadvantages of streaming rearview mirrors: Some streaming rearview mirrors have rear cameras located on the exterior of the vehicle. If the vehicle encounters mud, water, or other contaminants while driving, these can obscure the camera, resulting in a "blind spot" in the rearview mirror and posing certain safety hazards.

As a seasoned driver with decades of experience, I fully understand why streaming media rearview mirrors were banned—primarily due to too many safety hazards. They use cameras and screens to display images, unlike traditional mirrors that directly reflect light, which introduces a series of issues. For example, image display delays—even a half-second lag in response—can lead to misjudging the distance of vehicles behind you, potentially causing major accidents. Environmental factors also play a big role: in rainy weather, water obscuring the lens makes visibility poor; at night, low light results in blurry images; and under strong light, the screen glare becomes unbearable, making it completely unreliable. Traditional mirrors are straightforward and always functional, with no worries about power failure or system malfunctions. These risks naturally concern regulatory authorities, leading to the outright ban—all to ensure road safety. In the long run, these mirrors might be unbanned once the technology matures, but for now, the risks are simply too high.

From a technical perspective, the ban on streaming rearview mirrors stems from their inherent technical flaws that are hard to overcome. Camera systems perform extremely unstable in low-light or rainy conditions, and screen displays often suffer from latency issues—just 0.1 seconds of lag can lead to critical misjudgment in emergencies. The display is also prone to interference from strong light reflections, and improper angle adjustments can render it completely unreadable. Traditional rearview mirrors are far simpler and more reliable, with purely mechanical structures that rarely fail and significantly lower costs. These defects are clearly recognized by regulators, making it too risky to allow them on the road. Future technological advancements, such as AI-enhanced real-time imaging, might eventually replace mirrors, but the current unreliability makes the ban necessary for now.

I tried using a streaming media rearview mirror while driving myself, and it really didn't feel reliable. The image had a delay, making me hesitate during critical moments like lane changes. Once on the highway, the screen suddenly went fuzzy, and I couldn't see any cars behind me—scared me half to death. I think it's too unreliable; it becomes useless in bad weather, and is a hassle, costing a lot to repair. Traditional mirrors are much more dependable—just a quick glance tells you everything. It makes perfect sense to ban them; safety tools need to be simple and efficient.

From the perspective of automotive safety standards, the ban on streaming rearview mirrors is primarily due to non-compliance with regulatory requirements. Traditional mirrors adhere to stringent optical standards ensuring reliable reflection, whereas digital systems carry risks of image lag or interruption, failing current safety tests. For instance, verification is required that cameras can operate continuously under extreme conditions; otherwise, there's no backup solution if they fail. Regulatory bodies must conduct comprehensive evaluations before approval is possible. The temporary ban safeguards public safety while encouraging manufacturers to enhance their technology.

Future automotive technology may popularize streaming rearview mirrors, but banning them now is necessary. The issue lies in the immaturity of the technology: image delay poses significant dangers during high-speed driving, cameras are prone to failure in rain or snow, and screen is more complex than traditional mirrors. The simple, reliable, and low-cost structure of conventional mirrors highlights their advantages. The ban is a transitional measure—once more stable systems are developed, their introduction can both reduce accident risks and drive innovation.
