| >It seems like most Americans genuinely believe they have not only a right to break the law when it comes to speed limits, but an obligation to speed. Or at least they drive like it. "I'm following the flow of traffic" as if other people breaking the law makes it OK? That seems to be a true sentiment, though[0][1][2]. Deviating significantly from the speed of actual traffic will likely lead to more accidents. Insisting stubbornly on following the letter of the law when it is actually detrimental to safety is not moral; it is merely pedantic. Fiat justitia ruat caelum is not a particularly healthy view of the relationship between the legal system and society. [0]: https://trid.trb.org/view/306976 (From the abstract: "A major influence on speed variance is the difference between the design speed and the posted speed limit. It was determined that speed variance will approach minimum values if the posted speed limit is between 5 and 10 mph lower than the design speed. Outside this range, speed variance increases with an increasing difference between the design speed and the posted speed limit. It was also found that drivers tend to drive at increasing speeds as the roadway geometric characteristics improve, regardless of the posted speed limit, and that accident rates do not necessarily increase with an increase in average speed but do increase with an increase in speed variance.") [1]: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=1904038 ("A model of the optimal speed limit is developed which explicitly recognizes the role of average speed, speed variance, and the level of enforcement. An unusual result emerges, namely that a higher speed limit may be optimal when reducing the variance in highway speeds reduces accident externalities.") [2]: https://www.fhwa.dot.gov/publications/research/safety/17098/... ("Separate studies by Solomon (1964) and Cirillo (1968) concluded that, as vehicle speeds deviated from the average speed of the traffic stream, crash involvement rates increased... Studies throughout the 1970s produced findings consistent with the research... For crash severity, higher vehicle operating speeds are associated with more severe crash outcomes. However, the relationship between crash frequency and speed is not as clear. There is some indication that increasing posted speed limits is associated with an increase in expected crash frequency; however, the relationship between operating speed and crash frequency has yet to be well established.") |
