ok...heres my take..
you were wrong in your assumption of right of way. That said at that point you seemed to have made the assumption he was letting across him...clearly he gave you that impression or you wouldn't have ridden across him I guess. But it appears you misunderstood him?
All of that is day to day stuff on the road...we all make mistakes. His actions after that point leave a lot to be desired. Personally I would not have told him to f orf given that it would have been my error in the first place...I think that is what triggered his moronic and dangerous and aggressive driving thereafter, which to me is unacceptable because he was seemingly deliberately trying to pursue and harass you.
I think, from what you say, a smile and a friendly wave instead of a f orf would have calmed this moron instead of releasing his small penis mentality even further.
jmho.
