I think the thread title deserves a quality response:

Why do any of you find it necessary to speed?
It is of course the wrong question. A better question might be: "Why do we have speeding laws and how should they be enforced?"
But that does nothing to address the essence of the original question.
My answer is: Speeding is a side effect of the safe driving process. Drivers must constantly manage speed relative to the immediate local conditions. If they drive to the speed limit they aren't doing it right, and sometimes will be dangerously wrong.
The idea that we should be able to seemlessly switch between setting speed to conditions below the speed limit, yet setting speed for legal reasons once the speed limit is reached is more than the human brain should be trusted to do. The key problem is that setting speed to conditions is a mainly subconscious activity, while setting speed to the speed limit (i.e. when the conditions would permit a higher speed than is legal) is mainly a conscious activity. Passing control of speed backwards and forwards between conscious and subconscious layers is NOT going to take place at exactly the right instant - and those driving to the legal limit will find themselves still driving at the limit even after those driving to the conditions have slowed down.
This is the exact reason that excessive speed crashes are INCREASING in the speed camera era.
And anyway, since experienced drivers do not need a speedo AT ALL to drive safely, driver time and attention spent on the speedo and speed limit is valuable time that could have been put to much better use looking out for hazards.
