Learners on motorway

truckman020:
,they cannot afford to make even the slightest mistake what with vehicles going past them at high speed,wonder how long it will be before a learner driver causes a pile up through doing something stupid by not listening to their instructor,it does happen as we all know

Is that any more likely to happen than it is if a new driver goes on to a motorway for the first time just after passing their test, but without any supervision?
