Evidently,anyone can run that defence successfully, in the unlikely event that they can show they have such special skills and the court is satisfied that they did not, beyond reasonable doubt, present any danger. Speed in itself is not conclusive ; the driving must be judged in all the circumstances of the case (DPP v Milton [2006] ) "Special skills " in a defence, however, has been doubted. There is a case where it was disapproved of but the disapproval was in the nature of a judicial aside, not part of the judgment, and so is not binding on lower courts (R v Bannister [2010]) The logic in the objection was that the standard set in the Road Traffic Act 1988 is "the way he drives falls far below what would be expected of a competent and careful driver" and "it would be obvious to a competent and careful driver that driving in that way would be dangerous" and so whether or not the defendant is an exceptionally skilful (or incompetent) is irrelevant; the court should not substitute "special skill" in a driver for that of the ordinary careful and competent driver.
We await a play-off ! Some case may arise in the Court of Appeal where that last view forms part of the judgment and "special skills" no longer apply.
