Put your foot down and pass before he pulls out.. How many times as this happened to you? and as a driver, how many times have you done this? Honestly!
I can honestly say I don't, since as a very long term cyclist I can see the danger in trying this, but yes, I have seen many drivers doing this and worse in these circumstances.
My attitude that I share road space, don't fight for it or demand it, influences my road behaviour, so I do what i can to help all other road users. That it delays me by microseconds each time doesn't bother me. Examples:
Cycling I use a mirror, yes, really use, so I time my parked car pass to not coincide with faster passing motor traffic. Alternatively where there are plenty of pavement cutaways and no pedestrians on a stretch of pavement, I pass a parked car on the nearside. On the narrow twisting lanes around here when drivers are stuck behind me, I wave them through the moment I see the way ahead for an overtake to minimise their delay.
Driving I always give way to public transport since that serves the whole community, not like me serving only me in my car. Cyclists get especial help to a degree some might feel extreme. For example recently, approaching a large roundabout I was aware of a cyclist's body language showing uncertainty, clear to me that he really wanted to go right through that dangerous roundabout but was uncertain hearing my approach. I slowed right down to his pace and gave him a gentle beep on the horn. As he looked around I leant right forward to the screen so he could clearly see me and with a smile waved him across in front of me. Momentarily surprised but then smiling, he passed across the front fully protected by the bulk of my car. That took far longer to explain than the second or so to do.
All this might give the impression of a very slow driver, but nothing could be further from the truth as my journey times show, I'm just slow where it's needed. However, I don't expect the same of other drivers. Many of them are relatively new and still gaining experience, many are under pressure of time for valid reasons, and some are simply incapable of performing to the same standards. Since the roads are for all of us I expect these and accordingly are tolerant. It's that tolerance that I do expect from everyone, if only because it precludes the all too common and dangerous road rage.
