Something that really bugs me!
Today parked in the street, pulling out the car in front was really close and so was the one to the rear, so I checked nothing was coming, street was clear so I began pulling out, concentrating on not hitting the car in front, suddenly Mini appears from behind squeezing though the gap between my car and the car parked on the other side of the road ( must have missed it by an inch), the woman giving me the v sign as she passed.
The same is true when in a car park, when you start to back out of a space and nothing is coming they should stop and give way not carrying on assuming that they have been seen
Surely I am IANBU to presume that if someone comes across a manoeuvring vehicle I would expect them to give way
