It must be somewhere near me, Backoff! We have a roundabout here, and through the village there are loads of '30MPH' signs and speed cameras. As you approach the roundabout it has a national speed limit sign - IMMEDIATELY behind that sign is one that says 'roundabout - reduce your speed'! Exactly where do you get to do the national speed limit?! Unless you have a 1-50 in 1 second car, the sign is useless!
