Following the lead from @ejstubbs I wrote to dvsa about the driving instructor driving/parking on the pavement.
Have to admit to being disappointed by the response.
" Thank you for your email of 26 August about the problems you have had with an approved driving instructor (ADI).
The ADI Registrar’s role is to ensure that the standard of instruction provided by ADIs is satisfactory, and the instructor is a ‘fit and proper’ person to remain on the Register.
The circumstances that you outline in your complaint are such that the ADI Registrar cannot get involved on this particular occasion.
I should point out that being an ADI is a notifiable occupation so, if you were to report this incident to the Police and the individual was charged, the Registrar would be made aware and could take appropriate action.
Alternatively, you could seek advice from your local the Citizens Advice Consumer Helpline who can be reached on 03454 04 05 06 about the best way to proceed. Citizens Advice will advise you on your rights and what further action you should take.
If they believe the matter needs investigating they will refer the matter to the relevant Trading Standards authority. If the outcome of such action is successful, I should be grateful if you could notify me."
