Have been babysitting my grandson in London and was taking him out in the pushchair, in order to reach a local park I have to pass a petrol station, and I needed to cross the exit for said station. A woman driving her car could quite clearly see me waiting with the pushchair for her to exit, however she couldn’t exit immediately due to having to wait for a break in the traffic, if she had pulled back - there was nobody behind her - just a short way, I could have crossed the exit instead of having to stand until she could pull out. This has happened to me countless times. My DH will always pull back to let a waiting pedestrian cross if waiting for a break in the traffic.
I just think some drivers are extremely selfish.
