Of course not.

Correct.

That was not the desired outcome. My desired outcome was to make reporting to the police go as smoothly for me as possible which I'd preferably entirely skip if not for the fact that insurer required me to report it.
Talking to the police (or anyone really) is a stressful event for me so any help with establishing what to say was very much appreciated.
On semi-related note my car is at repair shop for 3 months already and I have no idea how much longer will it be because apparently no supplier of catalytic converters is willing to estimate when they'll have a single item for Toyota Auris.
