It does not matter whether you agree or disagree with a particular speed limit, the law states that you MUST NOT exceed it. There can be no grey area there.
However it is true that speed in itself is not the problem in relation to road safety BUT ....... inappropriate speed IS.
Also, RAY C is quite correct with what he says about ACPO guidlines.

Thank you Geordie for the clarification of your point.
I cannot agree with it, or that of Colin, both of whom advocate breaking the speed limit to suit personal desires, rather than necessity. That is illegal, and immoral.
If a vehicle in front is driving erratically or you have concerns for your safety as a result of its behaviour, you must allow more space between it and you, to enable you to manage any hazard that it might present. You only overtake when it is safe to do so, and without having to break the moving traffic regulations i.e. speeding.
Meister has it about right, and there is no just reason to deliberately exceed the speed limit simply to overtake another vehicle. And before advanced drivers and motorcyclists start protesting about creating a safe space by accelerating away from a hazard, none of the official spokespersons from these organisations will say that their organisation supports the use of speeding for any normal road activity.
The safe speed given road and outfit conditions may be lower than the prevailing official maximum speed limit for any given stretch of highway.
Some food for thought, - The ACPO guidelines are just that, they have no basis in law, but they are the way that some (but not all police forces) interpret their responsibilities in pursuing prosecution under the speed regulations. It would not be a defence in law to claim the APCO guidelines as mitigating circumstances.
Some CPO's are advocating a zero tolerance to exceeding the prescribed speed limit, so watch out.
