The Flame Pit / Re: Motorway Gantry Cameras - activation.

It came up on Reddit, someone posted a dash cam video of being flashed as they were speeding up because a gantry went from 50 to 60 as they approached it, but their dashcam shows that they were under 60 when they were flashed (and the gantry was displaying 60).
No-one was overtaking/catching them, so it must have been them that triggered the flash.
I can't think of any other reason for the flash other than a camera test. (or a fault)
One would expect that as the confirmation photo would show 60 on the gantry so it shouldn't ever get sent out.
I suppose that technically they are still in a 50 from the previous sign until they pass the 60 sign and the measurement could be made before the sign (I thought HADECS cameras were self contained so the radar faces in the direction of travel though), but most likely the whole section went to 60 at the same time including the previous gantry anyway.
It would be an interesting day in Court if the measurement is behind the gantry to match the photo and they tried to infer speeding before the gantry from it.
