The training school car (which is the one I took my exam in) has a double set of pedals and additional mirrors so that the examiner can take over in case you do a horrible mistake. Which does happen quite a lot - some 20-30% of students fail the driving exam, and sometimes for nearly causing an accident (the examiner intervenes).
