Accident on gas station involvement?

Halllo together, I don’t know if this is correctly placed here, but I don’t think I’m quite right here. Vllt can still give me an assessment.The following has happened: I wanted to drive backwards to a tap column today.The view towards the gas stationArea said: free ride.Since I didn’t want to ram the tap column, I looked in the other direction to the tap column and sat back.And rumms I drove a lady into the side. mpolimit? She must have been on the road quite fast, otherwise I would have seen her come at the look shortly before.clear is,I drove backwards.a partial debt exists anyway.because the damage to my car (old and only stumped) is irrelevant, but the question is enormous on the opposing car (side) is now: there is a chance that there is actually only one partial debt for me.The lady has to see that I drive backwards,especially since I am already really close to how fast the lady really was will hopefully show the records of the surveillance cameras. The gas station is located directly in a bending forward road with speed limit 50. The pump lattice almost in straight out.Tempo would have been well possible. I am very grateful to you for your assessments, too experiences or professional tips,
