What is the evaluation of a driver who is driving more than 10 mph under the legal traffic speed?

When evaluating a driver who is driving more than 10 mph under the legal traffic speed, the assessment of "Control - Bad" reflects concerns regarding their ability to adapt to the flow of traffic. Driving significantly slower than the speed limit can create potential hazards on the road, as it may disrupt the established speed patterns of other vehicles. This discrepancy can lead to increased risks for both the slower driver and other road users, including forming obstacles that could make it difficult for vehicles to pass safely.

Drivers are generally expected to keep pace with traffic to ensure smooth and safe driving conditions. When a driver is operating below the speed limit by a considerable margin, it raises flags about their decision-making and overall driving proficiency. While it could stem from a variety of reasons—nervousness, unfamiliarity with the area, or even vehicle issues—such behavior can result in erratic driving patterns and ultimately poses a risk to safety on the road. Therefore, categorizing their control as "Bad" is appropriate given the potential dangers involved in driving significantly slower than the traffic speed.
