Car A conducting 3 point turn.
Reverses into driveway
Car A still on road, unsure if still occupying car B's lane for whole period, nose close to centre of road.
Car B passes in front of car A, Car B is squeezing past can see from their trajectory that they are mounting the kerb as they pass the front of car A.
Car A drove forward and makes contact to Car B's tail.
Cosmetic damage to car A.
Car B panel damage.
Car A doesn't intend to claim, Car B's insurance contacts driver A asking for statement / dashcam footage.
Car A has comprehensive insurance.
What is next course of action for A. Just file a claim and let insurers deal with it?
Is car B at fault if Car A is still occupying Car B's lane for whole period?
I feel it's likely Car A's fault unless it can be proved that car A was occupying car B's lane for the whole time.
I've just been using r/mspaint as therapy to help unsee that sketch
