I did this when I came back from the USA. I booked an hour with the lady who had taught me to drive so she could go round with me shouting “Drive on the left!"
did the car have plates the previous day ?
is there more than one driver of the car
I have to say I did dob in someone who said they were blind and couldnt drive
and then I saw her driving
I was blinder than her ( so the identification was uncertain )
and er in the passenger seat .... ( I was - not her !)
