The reliance on speed cameras to police our road system has distorted the
perception of what is safe. *As far as the cameras are concerned an idiot
driving 1 metre behind the car in front at 70mph and weaving all over the
road is perfectly safe, someone driving at a steady 60mph on a road designed
for 70+ but somebody has decided to designated as a 50 limit for no logical
reason is defined as driving dangerously.


Do you really think speed limits are in place because " somebody has decided to designate as a 50 limit for no logical reason"?
Any evidence for that assertion?

Is driving at a steady 60mph on a 50mph road "defined as driving
dangerously"? by anyone other than you?
A dangerous driving prosecution needs rather more in the way of danger
than exceeding a 50mph limit by 10mph.
And cameras do not have concerns. They only record a picture plus
data.
