Scooter hit, how do I keep going?

Hello together, while parking backwards I unfortunately missed a scooter and threw it over. There are some paint damage to be seen. Now the question arises as I proceed. I have read something through the internet and it was often recommended in such cases to have the insurances regulate the damage. If the resulting “upgradation” becomes too expensive, one could still pay back the damage to the insurance. Is this possible without further delay, or m Another question: I’m included in my father’s insurance policy. So I’m allowed to drive the car in insurance technology. He has a very high SF class. Does it make a difference whether he or I caused the accident?
