### Feasibility of Implementation  
While promising, we realize that other avenues of this system need further discussion before adoption. In particular, glare reduction could lead to drivers failing to recognize incoming vehicles due to their familiarity with conventional lighting systems. Furthermore, we did not investigate the impact of dust and prime accumulation on headlights and windscreens, which could potentially reduce the brightness of incoming light, thereby abating the perception of nearby vehicles. The latter issue is especially important since dust, grime, and other pollutants tend to accumulate on headlights and windshields in polluted or heavily trafficked areas, which could pose a safety hazard for cars using this lighting system.

Regarding the accumulation of dust, grime, and other particulates, it was discovered that detection distances were reduced due to their build-up on the windshield [23]. However, despite depolarization due to light striking the particulates, the degradation of detection distance was found to be less in the polarized system than in regular headlights. Nevertheless, regular cleaning of the windshield and headlamps are recommended for optimal performance.  
As discussed by [PERSON], the use of polarized headlights increases a driver's visibility of pedestrians [20]. Furthermore, according to a study by [PERSON] [23], the use of polarized headlights also increases the detection distances compared to the traditional system. It should be noted that the headlights used by [PERSON] and [PERSON] were halogen lamps. In this study, we determined that unpolarized LED headlights have a lighting distance of 155 m and 115 m when polarized. The halogen system's lighting distance was similar at 110 m. It is also worth mentioning that these measurements are taken from headlights in high-beam mode. Additionally, we believe that our polarized system's low-beam performance is akin to that of the halogen system, judging from their similar high-beam lighting distances. Regardless, further study into beam configurations is needed to quantify their impact on illumination distances. Since our modern polarized LED system possesses superior illuminance, a lower power rating, and comparable high-beam illumination distances to halogen lamps, this combination makes them well-suited for automotive lighting.  
Another glaring issue of this system is that its benefits might only be realized once it has been widely adopted. In our previous and most promising research [17; 21; 24], it is apparent that this system will only work if both vehicles are equipped with polarized headlights and windshields or flip plates. This fact also brings up the issue of glare reduction when multiple vehicles are present. For example, a third vehicle approaching from behind will shine its headlights through the back of a car, potentially blinding the driver due to the reflection in their mirrors. Further study is needed to determine whether the windows and mirrors need to be polarized as well.  
Despite some challenges and uncertainty, we believe that the widespread adoption of this system is prudent. As discussed by [PERSON] [19], the benefits of reducing accidents vastly outweigh the cost of installing polarized filters in cars. We also believe that further studies into the use of modern LEDs in Land's polarized lighting system would remove all doubt in its capabilities. Therefore, additional research is needed for the incorporation of our automotive lighting system.
