So, driving on the roadway from Helsinki, initial indicated speed limit of 100. Drops from 100> 80> 60 because of some ongoing work, in a distance of less than 500 meters.
I let the car coast down on its own, rather than applying the brakes. I guess I was around <70, but then there was this van parked there from which came a strong flash. I drove back and checked again, it seemed to be a hidden/ unmarked car, and every second car got flashed!

Dunno why they wouldn't keep the speed to a standard 60, rather than tricking the drivers with random speeds. But I guess this the "#€%&/( needs the money, so if you have to sell the mother, they'd do it! €%&/(. Frustrated!
Some questions:
I know that at least in the US, in some places, fines may be different if it is a work zone, and speed limits are temporary. Is that so here as well? Or it is similar to a standing camera? Or similar to the cops catching with radar?
Now, I am quite sure that the laws says that such measuring must be after 150 meters from the speed post, this was less than a 100 meters.
Anyway, I am just paranoid now! And I am sick of this country, its taxation on everything, and the fines, anything that helps them defraud the citizen! Personally, don't care about the broad! I love my kid though, but once it really gets to me, I need to dump all and move.
