The reasons why many people tend to drive slightly over the speed limit can vary and are influenced by a combination of factors:
Social norms: There may be a prevailing social norm or an unwritten rule among drivers that it is acceptable to drive slightly above the posted speed limit. People often observe the behavior of others on the road and adjust their own driving to match the perceived norm.
Flow of traffic: Drivers may choose to drive slightly faster to keep up with the flow of traffic. If the majority of vehicles around them are going slightly above the speed limit, they might feel compelled to do the same to avoid disrupting the traffic pattern or to maintain a smooth driving experience.
Time-saving mentality: Some drivers may exceed the speed limit in an attempt to save time or reach their destination faster. They might perceive a small increase in speed as a means to reduce travel time, even if the actual time saved is relatively minimal.
Perceived safety: Drivers may believe that going slightly faster than the speed limit is safer than driving at or below it. They might feel that it allows them to better match the speed of other vehicles, merge more easily, or maintain a safer distance from potential hazards.
Lack of enforcement: The perception that speed limits are not strictly enforced in certain areas can contribute to drivers feeling more comfortable exceeding the posted limit. If drivers believe they are unlikely to be pulled over or receive a ticket, they may be more inclined to drive at a higher speed.
It's important to note that exceeding the speed limit, even by a small margin, can still pose risks. Higher speeds reduce the time available to react to unexpected situations and increase the distance required to come to a stop. Adhering to speed limits helps maintain safer road conditions for everyone and reduces the likelihood of accidents.
