To think this woman should be thoroughly ashamed of herself?

If your son was waiting for a car parking space, then presumably he was stationary? If so, she reversed into a vehicle that wasn't moving and that immediately puts her at fault. The alternative is she's trying to suggest your son drove into a reversing vehicle (with its reverse lights all lit up.) Unlikely, I would have thought. I'd leave the matter with the insurance company to sort out.

You generally have 48 hours to report an incident to your insurers, even if you don't intend to make a claim.

Never trust a stranger to make good and pay your bills.

Report to the police. Suggest that a false insurance claim is being made by her.

Dear Lady in Range Rover,

I tried to give you the benefit of the doubt when you requested we avoid reporting to insurance but now you are trying to rip me off, so thankfully I have the CCTV which clearly shows that I was stopped and you reversed into my car. I will proceed with filing a claim with my insurance and reporting this to the police.

This is always the danger when people say "let's not go through the insurance".

Obviously tell your insurance company everything and don't speak to the woman again. Only communicate thru the insurance company. if you want to reply to her message just say you're taking legal advice and then block her.

Report it to his insurance company and give them her details. Ensure that he gives full details and plans of the circumstances of her crashing into him by reversing out of a parking space without checking the way was clear.

A similar thing happened to me, a woman reversed out of a parking space into my car, as I was slowly passing. She very reluctantly admitted it was her fault and gave me her details. The insurance companies sorted it out and mine said hers would just cough up because she was definitely at fault.

I believe so

If you reverse into someone it’s automatically your fault, right?
