bike rider doored by taxi, page-301

Might well be, but there was no accident as she did it on purpose.

Exchange details? For what? Unfortunately no damage to her or the bike, no damage to the taxi, so what was the next step? Maybe a Supreme Court trial to establish she is a deadest idiot, troublemaker and an unsafe road user?

While you're here, shouldn't she be charged with reckless riding, for taking both hands off the handlebars, whilst moving, and illegal parking as well?

"one thing indisputable is Its illegal to walk away from an accident scene , without giving details which is what those obese businessmen did"

Next time someone runs into your shopping trolley at the supermarket, make sure you have a pen and paper to get their details, after all you did just have an accident.

Hopefully no one is stupid enough to pass their "details" on to any moron that asks for them. If it warrants exchanging details, call the police, let them sort it out.
In this case there was no damage or injury to person or property, only her ego.
