How about it the DVLA being a usability car crash generally?
I just had to renew my photocard license. If you don't have a passport, then you have to do it offline through a properly equipped post office, which you can find by <URL that 404's> or <telephone number that's disconnected>. Rolling my eyes and just turning up at my local post office I discovered that they couldn't do it as their post office franshisee didn't want to pay many thousand quid for a machine with a non existant return on investment.
After visiting five seperate post offices in two seperate towns and encountering the same problem, the girl behind the counter at the last one suggested them doing a passport photo and then sending it off via the old paper form, which they did have.
It then transpires that the DVLA requires payment via cheque, which my bank is doing it's best to phase out so hasn't provided me with a cheque book. My bank also won't print single cheques and won't provide a bankers draft but can provide me with a cheque book in a "few weeks" at additional cost. (note that time taken to print and deliver cheque book is longer than the deadline from the DVLA for submitting the application) You can't post cash to the DVLA as their staff aren't trustworthy enough, and they won't do credit cards for a paper application.
Happily, my employer does have a cheque book for the business and was happy to write me one, so I got around it that way, but... FFS DVLA?! Could you make a simple job any more difficult?
