“Edge cases are probable scenarios that have a low probability of occurrence. These rare occurrences are easily missed and thus are often missing in datasets. While humans are naturally proficient at dealing with edge cases, the same cannot be said of AI.” -- Ofir Zuk 2022

Detours are one edge case that is very difficult for Advanced Driving Systems to handle.

RF-eye beacons give precise directions to vehicles to aid in navigating around detours.

Similarly, it provides solutions for other low probability encounters. For example, on signs with an image of animal, AVs may infer that an actual animal is there and stop abruptly. With RF-eye, the sign instructs the vehicles to be aware of possible crossings and to reduce speed.
