Your assessment of the guilt in a crash?

Since the question of guilt was not yet resolved in the event of an accident a week ago, I would be very pleased about your opinion. Should not have much to do with the topic of legal advice…. To the accident: About a week ago a golf abens drove in dense professional traffic on the right lane of a 2 lane road. There is no middle line, and on the right there are still cars on the road…. is therefore quite tight. Anyway, the golf swam with about 50 in traffic, As a few meters before this someone got quite comfortably out of his parking car. Since directly next to the golf another vehicle drove at the same speed, the gulf burst quite strongly, because the danger was very great to catch the disembarkation. At the height of the person concerned, a small car drove to the gulf, which could not brake any more in time. Fortunately, the gulf had a speed of about 10 – 20 km/h in the momennt, which led to the k one of the mentioned injuries involved had… .. a typical driving accident in professional traffic just…. However, the question of guilt was not resolved by the police on the spot, although it is quite clear to me. The above person, who got out of the car, blames the golfer alone, the driver of the driving small car again blames the golfer and the disembarking one partially…. so at least 5 minutes after the accident…. Police said after the accident, that one of the two drivers received a fine, and that would very likely be the small car driver, that is, the drive-in driver. The actual cause, namely the person who left her car casually and carelessly with a wide open door, was listed by the police as a witness only, but not as an accident involved. In my opinion, the Gulf is not at all to blame, since I see it as a matter of course, to slow down as soon as There is only the danger of approaching a person! It is annoying for the intruder, but the accident would have been avoidable if it had kept enough distance, or if it had reacted better…. anyway, I would be interested in your assessment.
