Final answer:
Visually impaired individuals pose the highest unpredictability and visibility challenge for drivers and pedestrians.
Explanation:
Visually impaired individuals are the most unpredictable and hardest to see pedestrians due to their limited vision, which can make them less aware of their surroundings and harder for others to notice.
In contrast, joggers, skaters, and children may have clearer visibility or make more predictable movements than visually impaired individuals.
With the advancement of technology like cameras and facial recognition software, tracking pedestrians and cyclists has become more feasible, increasing safety measures on roads and sidewalks.
