"all in a sudden there was this red car (FJA309) behind me and I ended up hitting it."
Of course it is your fault according to that. That means you wasn't even watching nor paying attention the whole time during reversing, and therefore ran into it yourself. A car is not a ghost, it can't be behind you all in a sudden.
