This is exactly the sort of situation when someone trying to squeeze through the gap might accidentally cause a rather nasty scratch down the the side of the twatmobile: or unforunately dislodge a wing mirror. Cyclists need to take great care not to do anything unintended.
Funnily enough, I said just as much to the fiftysomething woman with a fag and dyed blonde hair who was walking past and asked me why I was taking a picture. She stared at me for a few seconds, and I thought she was about to launch a tirade about cyclists on pavements or something. But then she cackled a smoker's cackle, and said cheerily 'Well, accidents will 'appen, I s'pose!".I felt strangely vindicated.
