I'd like to say people are treated fairly. Since the rules became more strict it is indeed nice to see players have a more lengthy ban based on situations.
Speaking of, All situations are different. All Game Moderators have different views on how they see certain situations, Some would kick as a "warning" Other would ban. It's all very different to each situation and Game Moderator.
From your image that you posted, I can't see much to go off, Assuming 2 trucks are ramming each other from what it seems, One would be at fault, But same again, Depends on the situation, Most would be a simple kick. However, there's always the option of reporting with a video of the same thing and see if they do get banned, given another person would handle it.
