28% of road fatalities are the result of excessive speed.
what percentage of these are within existing 30/40/50 speed limit zones.
Can the remaining be broken down into Motorway, A road and B roads?
35% of fatal accidents were the result of "loss of controll" which presumably wouldn't happen if you were at a sensible speed (i.e. taking a hairpin bend on a UC road at 59mph may not be sensible).
That's a bit of a sweeping generalisation - loss of control can be a rseult a wide range of things of which speed would only be a tiny fraction.
Statistics can be used to prove anything.
It's just moving us another step closer to a nice friendly totalitarian regime. Have a nice day now.
