Just so I can understand this, most people in this thread are criticising the cyclist for not doing a shoulder check, when a professionally trained driver, who should absolutely have anticipated that the cyclist was going to pull out, has to take evasive action for trying a dangerous overtake where there was clearly no room to do so? I think we're being a bit harsh here...
Completely unrealistic to expect the cyclist to wait for the bus to pull out, the bus driver presumably is doing mirror signal manoeuvre, so the cyclist would easily have been alongside the bus by the time he would have been pulling out, and bus drivers know to look for vehicles passing in these circumstances. At the speed the cyclist was travelling, he did exactly the right thing. And it's not as if he just pulled straight out into the right hand lane, he was moving across it from some way back. This is bad driving by the police car, plain and simple. Yes, it happens a lot, but of all the drivers on the road they ought to have known better. I would certainly put it into Roadsafe, so they have a record of it. I'm not sure he should have stopped in the road as he did without either putting on his hazard warning lights or some other indication to warn other drivers of the hazard he was creating in the road.
