If you say you cannot control a modern car at 75 on a clear road then I can only suspect a lack of ability or love of hyperbole.

I didn't say this. I said that 75 is the upper limit of my safe driving abilities under most conditions. And there's absolutely nothing wrong with that. There's plenty of people like me, too, and you share the roads with all of them.

I'm glad they have the cameras where you are, because they clearly need them there. Your lack of sensitivity to the other people with whom you share the road suggests to me that you are probably one of the people for whom the speed limits are set as low as they are.
