This is what will happen (for some) if new plans come to fruition.
It is not that bad an idea if the learner has had a number of hours tuition behind the wheel and their instructor thinks they are confident and able enough. Unfortunately there are large areas of the country where a motorway is not within reach, not even on a two hour, or more, lesson.
Another plan is for a minimum number of hours of tuition behind the wheel before a learner takes the test - 120 hours is mooted. I am against this. We all learn at different rates and many learner drivers are ready for the test way before they have done 120 hours. One-size-fits-all schemes rarely work in the way the wonks in their focus groups intended, and 120 hours is more than twice that needed for a private pilot's licence.
However, one plan is missing and that is the mandatory use of green P plates in the first year after passing the test. My two had them and they both said that most other drivers gave them a bit more leeway than after they were removed and this allowed them to build their confidence.
