Gardai wont record this. They are quite strong in their view on it. They are only there to ensure that all parties have licences and insurances.

This isn't my experience.
I pulled up on the inside lane behind a driver whose car was straddling two approach lanes and who had gone past the white line into the junction a little.
The driver of the car ahead suddenly reversed backwards and damaged my offside panel and door.
The driver hadn't seen me because I was in the nearside rear pillar blind spot and the driver had checked the nearside mirror.
I couldn't open my door and we were stuck at a junction so I called the guards and the driver called somebody to cancel a meeting/lunch.
The Garda and Beangarda arrived and they each asked us separately what had happened and then we talked together.
The circumstantial evidence could have supported a scenario where I ran into the car ahead, apart from the position of the glass fragments so this was good for me.
A few seconds after the drivers friend arrived and I could see by the conversation they had at a distance that advices were being given that could not now be acted upon with any credibility because of the drivers previous admission.
Admittedly this was eight years or so ago but it contradicts your comment and for a very simple reason.
It is possible they saw the scenario differently than I had - it was clear to me the driver was trying to back out of the junction, but reversing like that is an RTA and could have constituted either careless driving or dangerous driving if it had caused injury.
Regardless of this, the Gardaí are primarily there to gather evidence, question witnesses and present files to the DPP or the Courts.
As part of this they may inspect the insurance and tax and NCT discs, but checking details are available is not the limit of their remit.
FWIW
