car insurance claim - dashcam and phone

[Guest]

I was driving home behind my work colleague (sara). Slow moving traffic, clear conditions.
Sara stopped because she bumped into the car in front. It was less than 5mph impact.
The driver of the car got out and started shouting at Sara, so I also pulled over.
Sara's car is fine, no damage. The driver's car is also fine, no visible damage. But the driver then said her boot lid had been knocked slightly out of alignment. It was very slightly out of alignment. The boot still opens and closes. They both took photos.

The driver had a dashcam (we saw the dashcam in the window) and says this filmed Sara on her phone down the whole road (it's a long road, took maybe 5 minutes to drive down). She said she was calling the police, but she seemed to change her mind.

Sara admitted she was stupid - she'd answered the phone to her sister because her sister is in supported housing and only ever rings in emergencies. After losing her husband to suicide, Sara panicks in these situations. She explained this to the driver and apologised. She accepts blame as it was her fault.

Question - if the driver reports this to the police/insurance, is it going to be dangerous driving,careless driving or just the points for using her phone?

Sara is quite shaken up, she never normally does anything like that, and now she is worried about prison (she has anxiety)

I'm not independent as we work together - would I still be a witness?

Any advice?

Edit to add - Although I am a colleague, we don't actually know each other well (it's a huge car dealership) so could I be witness?

There is no point agonising over what may or may not happen.
Sara doesn't know if it will be reported to plod or not, but even if it is it will not result in a prison sentence.

Presumably the drivers exchanged details such as addresses and insurance details.
Sara should report the incident to her insurers (no need to mention mobile phone use) and advise them the other party might be making a claim.

You would be classed as a witness, but as you know Sara you would not be viewed as independent
