Why is it dangerous to drive too slowly?

Driving too slowly is dangerous primarily because it disrupts the traffic flow and increases collision risks. When a vehicle travels significantly below the speed limit, it creates a bottleneck in the roadway. Other drivers may then attempt to maneuver around the slow vehicle, which can lead to unsafe passing situations, sudden lane changes, or even rear-end collisions if following vehicles are not expecting such a drastic speed difference.

Moreover, when traffic flow is interrupted, it can create confusion and lead to reckless driving behaviors as frustrated drivers try to overtake or speed up to compensate for the slow-moving vehicle. This disruption can create a hazardous environment that is particularly dangerous in high-speed areas where a sudden decrease in speed is unexpected.

In contrast, the other choices either pertain to issues that aren't directly related to the safety risks posed by slow driving or involve different aspects of vehicle performance and driver perception that, while important, do not address the immediate dangers of slow driving in mixed-speed traffic scenarios.
