Granted, but in my world this behavior is not something that is imparted, in its entirity, overnight either.
The first thing to do is clearly to stop the rot in current drivers, but policymakers should not fall into the trap of letting new drivers go down the same path before they receive treatment. If we did nothing about existing drivers but produced safe new drivers, then the problem would be solved in about 50 years!
This topic has been touched on elsewhere with reference to speed and drink-drive courses, that are not provided to drivers until they have proven themselves to be a 'problem'.
The main difference between a pilot and a driver (besides the obvious third dimension

) is that until the day I retire I will not stop being trained, assessed, examined and standardised. While clearly the same thing would be prohibitively expensive for the millions of UK drivers, there is no reason why a 'lighter' version could not be implemented. I would at least like to see the driving test cease to be the one-shot 'rite of passage' into full driverdom that it is today.
I know we have discussed many other ideas regarding driver training, and I will not regurgitate them here, but it is clear enough that catching drivers early and instilling good practice is far preferable to remedial action later.
I appreciate that our roads are relatively safe, but if they were safe enough that we could all throw our hands up and go home then this site would not exist! As it is, we can see the downwards curve beginning to reverse already, and noone wants it to become a parabola!
My point is that, while a 'nudging' approach may be the way forward for existing drivers, there is no reason why a step-change could not be implemented for new drivers.
