Code violation vs dangerous driving
I'm no lawyer, but I believe that breaking the speed limit is an "absolute" or "technical" offence, in that provided that the facts are proven (it was you, and you were going at speed X) you are guilty.
Whereas dangerous driving depends on the PRECISE conditions (visibility, traffic, weather, car etc) and your behaviour at the wheel.
So, "speeding" may be safe (or not), but is still illegal. Dangerous driving is, by definition, dangerous.
The Safe Speed campaign probably reflects the law on dangerous driving, which is all based on circumstances. Exceeding the posted speed limit CAN be safe, and dangerous driving can happen below the speed limit.
To those who would condemn this man I say - you are probably right, but you can't be sure until you get ALL the facts, which you won't get from a Register article, or the BBC.
This is why we have a complex, expensive legal system, and not "trial by Register comments".
FWIW, sports cars don't generally stop significantly quicker than other road cars; most modern cars have enough brake and tyre performance to do ONE emergency stop from VMAX - or else the manufacturers would get sued for selling a product not fit for purpose. And if I was to choose a car for quick direction changes under heavy braking, it wouldn't be the arse-engined 911, PASM or not.
