Of course it is, but rarely a good one.
I attended a council meeting on road safety recently and had to listen to them discussing making half of the county even slower than now, lots of reasons, less pollution (doubt that makes fuck all difference) less noise (is the noise problem the law abiding or the twats with illegal exhausts that law enforcement do fuck all about) and on of my favourites was that the slower they make us all drive the more likely we are to go on the bus.
Cannot remember anything to do with Road Safety cropping up....
....but next time you wonder why a nice open stretch of road that was a 60 is now a 40, it's probably because that is about all the bus can get up to, so best you hop on that next time.
Those making the policies are typically out of touch, almost certainly not ridden a motorcycle or driven a truck in their life, and without a doubt never taken advanced training, but they probably identify as a gay toaster, which makes them perfectly suitable for the job.
As for Switzerland, the speed traps are almost exclusively on the straight bits, and often on the approach to a nice set of twisties, but avoiding eye watering fines means it can be difficult to get a nice flow on a modern bike, you can enjoy the curves, but as you exit one curve you need to immediately brake as you get upright - which is fine when it is for the next curve, but a chore when it is simply to try and avoid a ticket on the following straight.
It can be a right chore on longer straight sections, which is why I much prefer the French Alps, Vercors, Tarn Gorge as you can just ride what I would call "normally", wafting along with a nice flow and unless you go a bit bonkers on the straights nothing worse than a @£100 fine is likely to happen.
