With respect,
How do you define a dangerous and fast road ? In my mind there is no such thing.
It’s like saying the fast lane on a 3 lane m/way, it doesn’t exists. Roads per se are not dangerous it’s the users who can be a danger to themselves and others because they drive beyond their capabilities, skill level and fail to drive to the conditions of the road.
Certain roads throughout the country are given a bad reputation and are classed as dangerous but in the majority of cases it’s pilot error.
I’m fully aware of the cat and fiddle and have driven and ridden it many times and survived because I drove / rode within my skill level.
Motorists need protecting from themselves hence speed limits.
Theoretically speaking if everybody drove to the conditions of the road and within their capabilities then there would be no need for speed limits.
I suppose I have opened up a can of worms with the above but hey ho that’s what the forums are for, discussion.
Happy motoring
