I suggest you take a course in statistics.
Note I am not saying WHY the speeding motorists (as a group) have less accidents than non-speeding ones (though I might speculate), or that there is a causal link - but that they do (if the figures are anywhere near correct) is beyond doubt.
It could, just for example, be that the speeding motorists are mainly more experienced drivers, or lots of other factors which might make them have less (and a helluva lot less) accidents. But they DO have (if the figures are correct and see no reason for the DFT to rig them) have considerably less fatal accidents and VASTLY less more minor ones.
I know you may find that hard to believe, but it's not a particularly new finding. 30 years ago it was suggested that motorists driving at the 85 percentile speed were the least likely to have an accident.(the speed where 85% of motorist actually drive more slowly and 15% more quickly). Indeed it's been an argument for raising the 70 limit to 80 for a long time. Now I don't have the figures on which that was based, and in any case it's very old information - but I do have in this case which points extremely strongly in the same direction.
I think you need to point to the flaws in the figures or the logic - which oddly no-one has, rather making some unsubstantiated assertion.
