I couldn't care less about cameras. It's the limit signs I'm looking for. If I've seen those, the cameras are irrelevant. And if I see the camera but not the sign, I'm no better off anyway.
There certainly are places where signing is poor. I think the sense of the original comment was to recognise your point that 30 should be assumed in residential areas, in the absence of evidence to the contrary. So it's more usually a case of going "too slow" than too fast.
But that's exactly what I was trying to say in the bit you haven't quoted:
Poor signage can be a problem but IME around here, that's most obvious with intermittent repeaters in a 40. That only occurs on a "derestricted road" ie lamp posts meaning 30mph but speed limit relaxed to 40. The failsafe is to assume lampposts and no repeaters is a 30, rather than a 40 with the repeaters missing.
Reference has been made to speed awareness courses and to save anybody going on one to learn the speed limits applicable where there are no repeater signs I'll offer this (which is subject to speed limits for specific vehicle types.)
Lamp posts = 30 mph
No lamp posts on a single carriageway road = 60mph
No lamp posts on a dual carriageway = 70mph.
PS Forgot to say that the repeaters can be other speeds than 40, including 20, but when I wrote IME, I meant that it's only in 40 zones where I ever see such extended distances between repeaters that doubt arises.
