We can all moan about other drivers on the motorway and probably have a few faults ourselves. Why, because we are not taught how to drive on motorways.It requires skill and awareness but the technique has to be learnt. If we are not told any differently we end up tail gating, hogging the middle lane, rubber necking the list goes on.
Surely after passing the driving test, motorway instruction should be compulsary and you shouldn't be allowed on the motorway until you can prove your competence.
I have even witnessed people regarding the slipway on joining the motorway as a T Junction and actually stopping.
