Speed cameras not the answer
Speed cameras that cost €65m -- crisis, what crisis? They will do nothing to address limits set so low that motorists do not respect them, nor to catch the lethal bullies who routinely drive two feet behind any car keeping the limit.
It is not fast driving so much as dangerous driving which needs to be curtailed -- and speed cameras, which encourage drivers to constantly take their eyes off the road, are the wrong solution to the wrong problem.
To change attitudes I would suggest the replacement of catch-you-out speed limits (which involve drivers in frequent checking) with speed recommendations (around which it is safe to drive) and in the event of an accident a massive increase in penalty for wilfully disregarding the recommendation.
