If no hazard was there, would he have lost control? I don't know, possibly not.
If any other hazard had been there, would he have lost control? I don't know, it is possible.
Is a driver's loss of control the fault of the hazard or the fault of the driver? Barring exceptional circumstances, it's the fault of the driver.
This rider still had two choices they did not take 1) Simply carry on and accept the fine, 2) Come off the trottle and hope. There was, of course, a third choice; not to speed in the first place.
I was riding with someone who went off the road because they were surprised by an AA van cresting a bridge (correct side of the road, not speeding, good visibility). They were very lucky not to go head-first into the armco (or the barbed-wire fence beyond). Was the crash fault of the AA van driver? No. It was the fault of the biker, the bridge and the junction beyond to the motorway were clearly visible; they should have been planning ahead. Luckily in this case, the only major damage was to pride (and the bike).
@wesley01 - You make some valid points and there is some controversy over how road safety figures get massaged, err, reported (I've already mentiond allowig for regression to the mean). As for safety measures, have you tried asking you local council/roads authority why they don't fit them?
This is a quote from another source "When the bike fell, Mr Rowsell hit one of the upright supports of the crash barrier." He suffered a severed arm and a fractured skull. Maybe a bike-safe barrier would have saved his life?
