The more I look at this, the more I think the cyclist was an idiot.

Cab pulls over to the side of the road and stops - at a distance from the curb that's reasonable for a parked car. Cyclist tries to squeeze between stopped cab and curb and is surprised when a passenger gets out of the stopped cab.

She not only put herself in a blind spot where the passenger opening the door simply could not see her, she put herself in that blind spot where there was no expectation whatsoever that she'd be there. It's not like she was in the blind spot of a car while both were flowing in moving traffic.

Had she been trolling for a dooring she couldn't have done it any better.

On edit - and the more I think about it, the dodgier she seems. Geez, the first words out of her mouth were to ask for his personal information, as if the dooring was no surprise. I seriously doubt if I were surprised by a dooring I'd pop up off the pavement like an overly-caffeinated Weeble, instantly demanding identifying information to the point of knowing and very, very quickly stating the person opening the door committed a traffic violation.
