"when I realised she was going to carry on I shouted, blew my horn and braked as hard as I could."
Anyone who knows me can confirm I'm definitely not on the side of drivers in this kind of thing, but just to be completely fair in this context, one could argue that a driver can honk and brake hard simultaneously, while a cyclist will usually need both hands for optimal braking performance. So operating an airhorn at the same time probably doesn't really work - though shouting would, of course.
