Are these worth it? carriage way bridge camera got me 82mph. My satnav displays "mobile camera zones" are the road angel's any better for this or not worth it?

I know I could just do the speed limit but sometimes I forget!

 

83mph in a ?? zone...

 

70 zone

 

with the 10% rule you may be lucky......

 

Only as good at other uses. If other road angel people use similar route they are good.
