He saw you, he disregarded you. I had the same thing happen to me on a four lane arterial highway early one morning. Very low traffic, great visibililty. I hear a truck approaching from the rear. I am at the right side tire mark of the right lane. Nobody is in the left lane. I can tell by the engine sound that they guy is going fast and has not let off the gas at all. Dude almost clips me with the mirror of a 25' long delilvery van.

Why? because he could. I got the name of the company - and Italian food store - and sent them a letter. Never heard a word back from them.
