I have followed a car home this afternoon. Two people in it so possibly a lesson but no visible signs of a driving school, only indication was a P plate on the rear windscreen (so presumably the driver has passed a test)
The driving was appalling, misjudging corners, painfully overcautious, unable to pull out of a junction. The car behind me was hooting his horn at this point which would have made the driver more flustered but even so, it was quite dreadful.
To make matters worse the car was heading down a main road at school pick up time and past the county hospital A&E entrance (thankfully we never met an ambulance)
Now I'm aware that everyone has to learn and some people are more confident drivers than others. I just personally felt that whoever had taken the decision to drive that particular way (driver or passenger/ instructor) at that particular time had made a grave error of judgement and it can no way have done anything to build up the drivers confidence
