I was driving home from Cambridge last night on said road, heading towards Bury St. Edmunds.. noticed there was a new speed camera under covers ready to enforce a relatively straight section of triple-carriageway near the Cambs-Suffolk border. I was baffled as to the point of it - this will be a prime example of a camera where people slow down for the limit and then put their foot down when out of range.
Incidentally, I've never had a problem doing 80-90 down there, which isn't often as my primitive 1-litre AX gets too noisy for me to want to sustain that sort of speed

(Edit: Btw when I'm travelling down there it's usually around 9:30pm on Tuesday nights, nothing more than a few HGVs and a couple of other cars about. My worst speeding is usually travelling to and from Ipswich games on another stretch of the A14 round Ipswich, where I more consistently reach 85-90mph and it's only a dual-carriageway and busier).
I don't know what was said in the debate but I have a feeling it was little more than a PR exercise and that speed cameras were the intention the whole time. Is anyone with any authority on the issue actually paying any attention to all this criticism of speed enforcement and speed camera road safety policy?
