Legal information needs to be disregarded with regard to legal action!

Hello, I have an appointment in court this month and would like to get some information here in advance. To the situation: -30 zone – on my side of the road there are a number of parked cars on my lane – on the other side of the road there are vehicles in parking bays – Resulting road width approx. 4.5- 5m Accident: I come with my car to the narrow spot and see that an Astra comes to me, because the Astra drives nicely on its right track, I also drive right orienti a few days later, I get an accusation that the Astra has gone into a parked vehicle, which was parked in the parking bay, and that I should pay for the damage (100Euro) plus illegality plus 1 point, because I should not have observed the legal driving regulations. Since I have an legal protection insurance I have filed an appeal and now it comes to the trial. How do you see this case? Is there a minimum width for the vehicles where I have to wait? He hasn’t touched my vehicle so I can’t help it if he can’t estimate his car properly? Would be very grateful for qualified answers! Greetings battery changer
