Thankfully, I have not use at all for a driving licence. I have, however, recently renewed my passport and getting a photograph that satisfied them was nearly impossible. You can't smile, you can't blink, you can't turn your head slightly, you have to have you eyes and top of head in line with some imaginary line, whether your anatomy allows for that or not and they dithered over whether my eyes were too far apart. For God's sake, I'm weird-looking enough for NO ONE to be able to pass themselves off as me!
