Re: Wrong question
Road safety went IMHO off a cliff after speeding fines were automated via cameras instead of putting people on the road.
It's no coincidence that road casualty numbers have recently been increasing in the UK, and are now trending the same way in France just after the French government started installing revenue cameras everywhere.
Maybe some of these university boffins could run a study into that correlation? Methinks the grant money might be hard to find, though.
