I understand that the policeman who was exploring the capabilities of his patrol vehicle may well be prosecuted for his actions. Has he not been put through enough anguish? – I cannot imagine that he would be repeating the offence. Incidentally, Vauxhall have brought out a faster version of the Vectra which would do 160mph without the aid of a following wind and a vivid imagination – but then police drivers will not be capable of handling the vehicle at speed since they would not have had sufficient experience to drive fast.
