Just got notification of a speeding fine for doing 72mph in a 60mph on the M5 North between J17 & J16 just south of M4 interchange. It was a variable speed camera. I'd got no idea there was 60 mph on any bits of Mway. So I looked it up and it's the 3rd most prolific camera in the UK. The 7 most prolific are all in Avon and Somerset on the M4/M5/M32 around Bristol. Not somewhere I often visit but thought it worth a heads up to some of you who probably do.
