So if 85% or other drivers exceed the speed limit, thus breaking the law, we should break the law too?
Sorry, I can't agree to that. Speed limits are maximum speed limits (except for maybe two roads I've seen in my entire life that stated a minimum speed -- 40 MPH -- in addition to the maximum limit). It's not unlawful to drive slower than the posted speed limit. It IS unlawful to drive faster.
Hawk, just because a limit is posted does not automatically make it either practical or safe. Legality notwithstanding, maintaining the same speed as 85th percentile drivers around you is, statistically speaking, the safest way to travel.
This.
By the same logic, if 85 percent of the drivers obeyed the speed limit, then by your analysis driving at the speed limit would magically become safe.
I stand by my statement. The fact that 85 percent of drivers routinely exceed the speed limit, coupled with the fact that it is the differentials in speed that can be dangerous, doesn't mean that the one person who obeys the speed limits (which are set according to traffic engineering analyses for safety) is creating an unsafe condition. Rather, it's the 85 percent who choose to ignore the legal limit who are creating the unsafe condition.
It is not magic, merely reality.
Your statement stands on its knees, after having taken a blow to the solar plexus by numerous traffic studies over the decades.
Posted speed limits have little to do with actual highway safety. If the 85th percentile is above the posted limit, it is the dumbass lawmakers and regulators who are creating the unsafe conditions.
Speeding tickets are a racket, where the gov't extorts cash from those using the taxpayer-funded highways. They have nearly zero moral content and are merely an irregularly assessed use tax.
