Got the double flash last week in france, luckily it's the wifes car......
I was pulling out a junction turning left , out a 90km/h zone.
Pulling onto carriageway and up to 90 as traffic now behind, and lorry coming from other direction. only to see a 70 and then immediatly a Gatso, and then a 90 just after....
Guessing the junction section was all 70, but there were no restriction speed notices the way we came up to it... just a 70 repeater before the camera.
I saved the dashcam footage, and there was no 70's except for immediatly before the camera, and no way to see the sign before pulling out.
At least it was before Jan 2017 :-)
