Final answer:
Over-estimating your ability to assess traffic or roadway conditions most likely leads to risky behaviors and accidents due to overconfidence, which is influenced by the Dunning-Kruger effect. The correct option is c.
Step-by-step explanation:
Over-estimating your ability to assess traffic or roadway conditions can result in c) Risky behaviors and accidents. This is because a misjudgment of one's own skills, often due to the Dunning-Kruger effect, can lead to overconfidence. This cognitive bias is when people with limited knowledge or experience in a particular task believe their competence is higher than it actually is, compared to others with more knowledge.
On the road, this can translate into taking unnecessary risks, such as speeding, aggressive driving, or neglecting safety practices, all of which increase the likelihood of accidents. Hence, c is the correct option.
