That was very close, and unacceptable behaviour. The offender overtook his colleague who was stopped, and who was also blocking his view of anything approaching from the left. Why has he ignored his stopped colleague and just driven out? Because he's taking a gamble, based on his training and experience. I''m not expecting there should be a major enquiry, but I think a complaint is in order, and some reassurance that the offender will be given some feedback and advice regarding his experience and training. Why? Because I don't see why the public should be exposed to such risks or even so much as a fright, by those whose job it is to protect and help us to feel safe.
