With the current large scale introduction of automotive LIDAR sensors, cars will enjoy new possibilities with new rising features for active safety. Nevertheless, the vehicle is turned into a laser product due to LIDARs and other laser-based technologies. LIDAR applications usually are within the spectral range of Si-detectors due to their superior price point. These wavelengths are especially dangerous for the retina since the cornea and the vitreous humor are practically transparent for them, whereas the according light is still fully focusable by the lens of the human eye. The international laser safety standard IEC 60825-1 defines situations in which worst case scenarios are applied to test systems for their laser safety classification. In this paper, different situations are discussed which might not be obvious as being a laser safety hazard. Reconstructing these situations leads to the insight that the accommodation of the eye will take a crucial role of the laser safety of such automotive LIDAR systems, especially for complex systems consisting of multiple LIDAR sensors. It is shown that the eye safety hazard can be shifting within time and space. With this information in mind, the concept of Virtual Protective Housing should be tackled and reopened. The concept is explored from the view of functional safety as it is defined in the automotive standard ISO 26262.
