Barbara Castle, politician, brought out the 70mph limit after a publicity stunt by jaguar (e type) did 150 mph I think, and this was followed by ac cobra doing around 170.My speedo is pretty accurate so I don't really have any leeway. I do try to stick at 70mph, in reality according to the sat nav this is only 68 but I do sometime drift over 70! Zero tolerance policing will not work, there has to be some leeway IMO. 80 is too high but they need to be reasonable. To speed for just 0.1 of a journey should not result in a conviction especially if you were only just over the posted limit.
Bear in mind that the average Jo could only buy a moggy thousand or a Ford anglia, which could barely break 70!
Crossply tyres and drum brakes, leaf springs etc it was understandably so. But the 70 limit in my opinion is just as antiquated.
100 is perfectly safe in modern cars, providing the conditions and traffic are appropriate.
