At risk of starting a helmet debate - that's not my intention, bear with me - why does he opine that he'll "never leave my helmet at home again"? Does he wear it over his face? Does his Giro have pedestrian repellent properties?
There's no evidence the woman was anything other than stupid and/or negligent. He may mot like to hear it, but to be a dumbest in such circumstances is not a crime, offence, non compliance, or otherwise a matter for the police. So why is he berating the police for not being interested when they're quite right not to be interested? It's not the job of the police to issue incident numbers to facilitate financial transactions with insurers any more than it is the job of GPs or A and E to act as evidence gathers for insurers, despite victims and insurers using them as such.
I can see why the guy is aggrieved, but it seems it's everyone's fault but his. Ride in a manner that permits you to stop in the distance you can see to be clear. He describes how the pavement is thronging with pedestrians, so why was he not riding in a manner that would account for chumps who dive out without looking, as pedestrians are won't to do?
Sympathy quotient - Nil.
