(Edit: 1.6 kph= 1 mph)
In Germany certainly.
Fines for exceeding speedlimits in areas that are speed limited (which are the vast majority of paved roads here)
are quite steep and go up to and including loss of license.
In principle, exceeding the speed limit by 28 kph may results in loss of license, discretion of the local court.
A drivers license costs thousands of dollars in germany (this is a simplification but broadly true)
Also speedlimits in germany often do not legally need to be posted, as the type of road that it is, has an implied speed limit, posted or not.
People learn during drivers licencing which type of roads have which limits.
And the exceptions, up or down, in limit are often what gets posted.
On the autobahn is usually posted 120 kph, 130 kph or unlimited since the autobahn can have different limits depending on curves, traffic history at the location and of course construction (and in construction any lower limit is possible)
So this can make it a big tricky.
as recently as 10 years ago communties would strive for fairness and not set up an automated radar trap box (they are ubiqitous here) for hundreds of meters after an unlimited zone, to give you time to coast down and not have to slam on the brakes on spotted the sign, to protect your license.
But this has changed, now communties want/need the money (if I say why, this would be considered political by some and might get the post censored, sad that we have to self censor)
Say a 100 kph limit due to upcoming construction and you are going 100 mph (=160kph) you need to break pretty hard if the radar is right behind the speed limit sign.
I had a near miss going 137 kph in a 130 kph zone and 40 yards after another 130 kph sign a 100 kph sign had been set up and 50 yards after that the radar trap.
So think I just saw a 130 kph sign and I am good, overlook the 100 kph sign (because who looks for another traffic sign if u just seen one, eyes on the road right?) but I suddenly got a funny feeling and let off the gas..
still coasted with 129 kph past the radar machine.
Would have been enough for loss of license, but luckily another vehicle was block the line of sight to the speed trap...and i never got the ticket mailed.
It is quite difficult to fight tickets here as the radar trap machine takes a pic of the licence plate and your face.
Its a form back backdoor taxation of drivers, consist with the goverments desire to make driving as expensive, and therefore rare, as possible, w/o triggering a voter revolt.
And most drivers ares resigned to this taxation clad as a "safety" meaure
