The woman appears to be milking it a bit but she was hurt and probably egged on by the press.
It was discussed on Jeremy Vine not long ago, Ann Hegerty was on panel and spoke very sensibly about how the two parties are not supposed to talk to eachother after an accident, they exchange details. The police told Prince Philip not to go over but he did ask if they were alright. Since then the 'palace' have sent the best of wishes. He was breathalysed, taken to hospital to be checked over. No more than that can be done at the moment.
Philip's insurance will pay out, he will most likely be fined but do we know who was at fault, was it 'knock for knock', or whatever. He's not above the law, other royals have paid fines for driving offences.
Regarding him not wearing a seat belt, he may be exempt, some people are for various medical conditions but I don't know about him. I can imagine at 97 he might have very creaky shoulders. He could be fined for not wearing a belt but we aren't going to hear about it one way or the other.
Personally I think 97 is too old to be driving on public roads. Perhaps he will think the same now, especially if his wife and children give him a good telling off.
I'm glad no-one was killed.
Jeremy Vine is milking it too! Everyone is piling in. Ann Hegerty says you never apologise in a case like this even if you know it is your fault, she is citing her own experience where she admitted later she was at fault but it was for her insurance company to sort it.
