Digger,
A few things that I had to "laugh" at with your case are:
A) even though the driver admitted that it was unsafe to pass i.e. there was traffic in the opposing lane, he still felt that he had the "right" to "force" you off of the road and pass you anyway.
B) that sadly like too many, he believes the "no harm, no foul" given his testimony of "I didn't hit him, so why are we here?"
C) again sadly like too many he feels that because he's driving the larger, heavier, faster vehicle that that gives him more "right" to be on the road.
I'm glad to hear that everything worked out for you.
