In those situations I tend to use a forceful hand signal well ahead of my pull out point to indicate my intention to pull out and to encourage a following driver to hang back. I had a look at your shadow when you passed through patches of sunlight and there was no evidence of you signalling.
I'm not saying you didn't, and I'm not siding with the driver, but you may want to consider doing a longer held forceful indication in similar situations. Just a thought.
