I'm a new driver (~6 months) who used to cycle a lot in the past (I stopped due to one ride where there two collisions involving cyclists and cars and a further severe car-car collision all in the space of about an hour), but I've always overlooked considering the door zone for oncoming cyclists on narrow roads.

Thanks for your comment, it's highlighted to me a shortcoming of my driving that I'd never properly considered - and I don't expect I'm alone. I've watched lots of YouTube videos by driving instructors looking at footage of their students and compilations of dashcams and haven't once seen such a simple and obvious thing highlighted, which is probably a little worrying.
