Not sure if anyone has spotted them, but the new cameras on the junctions through West Hendon all the way through to Golders Green, they are light jumping cameras AND speed cameras.
Got flashed yesterday, just waiting for (another) speeding ticket 
Yeah, they’re also on the A1 between the A41 and A406
There are loads of them springing up
