Regarding average speed cameras on the A16, I have not lived in the area for long, but I find that driving habits are, on the whole, shocking.
I use this stretch of road every day and have witnessed two fatal accidents at the junction with the B1166 for Hulls Drove in Crowland.
Although I can see the reason for the cameras, surely it would be more cost effective measure and safer to install a roundabout at the junction.
It would slow traffic while enabling motorists going from Crowland to Gedney to cross safely, instead of taking their lives in their hands.
Whoever makes these decisions has no common sense.
