The problem here is that the other guy got his story in to the cop first. The first story you hear is usually the easiest to believe. If the other guy calmed down, told a nice story, and bonded with the cop over his big 4WD and they had a laugh about the guy in the Porsche, it's not hard to see how the cop fell for it. The truck tells a simple and common story of someone cutting in and getting rear-ended, you tell a complex and unusual story of someone deliberately ramming you.

The case will boil down to your word against his unless you can find some physical evidence to support you. You said that he hit you twice. Is there any way you can preserve the evidence and show two separate hits, one accidental and one intentional, that proves the story as you describe it? I would think that two separate hits will destroy any cover story he can come up with.
