Its a normal width road, you can easily get 2 cars past each other on the road. Not a busy road as its a dead end. If there are no other spaces available would you park opposite someone's drive, leaving enough room for them to get in and out but it would make it a bit tight.
I did this over the weekend and have had a snotty note put under my wiper "you are causing an obstruction, next time I'm calling the police".
I think the tone of the note has got my back up and am tempted to put a note through their door saying "call the police all you want, no yellow lines so I can park there"
