Maybe I never mentioned Germany because -
"The overall safety record of autobahns is comparable to other European motorways"
" Contrary to popular belief, only 40% of the autobahn has an unrestricted speed limit. The "recommended speed" is 130 km/h (80 mph)"
"The German autobahns are famous for being some of the few public roads in the world without blanket speed limits for cars and motorcycles. Lack of blanket speed limits does not appear to negatively impact the road safety of autobahns compared with motorways in other countries; motorways are safer than other road types"
"The average speed traveled on the autobahn in unregulated areas by automobiles not regulated by other laws is about 150 km/h (93 mph). On average, about three fourths of the total length of the German autobahn network has no speed limit, about one fourth has a permanent limit, and the remaining parts have a temporary limit for a number of reasons"
Germany has the highest number of cars in Europe I believe and a safety record that is on a par with ours. Autobahns are also patroled by unmarked police cars, if you take into account the unrestricted speeds in places and the average of over 90mph on those sections allowing drivers to put there foot down where possible seems to work pretty well.
It's just a pity that British authorities don't catch on to the problems they cause with their silly road speeds.
The point about people braking cameras still applies to people under the speed limit the camera is set for. My point re "most drivers" is based on data of Average UK motorway speed which is around 90 mph also there is oficial UK data that says over 57% of drivers exceed 30mph limits.
And Safety Camera Partnership operatives off the record have stated that they make more revenue by siting cameras where most drivers are over the limit due to the road or surrounding conditions such as change of speed limit not where the road is considered to be dangerous.
