Of course you were all hyped up on adrenalin, so it is hard to get beyond the yelling stage. But bottom line, since you were at or over the speed of traffic, likely you were well within the laws to take up any lane.
When the motorist started yelling at you, you needed to just ask the driver to quote you the law... and then be prepared to quote the proper law back.
Now that we have discussed the solution, go make up some cards, that you can tuck into a bag or pocket, that list the bike laws for your state... and be prepared to present those to the next "road lawyer" that directs you to "the bike street..." The problem with this jackhole is that he made up what he thought were the laws... and no one has ever told him different... and like many many motorists out on the street, they think they are just doing cyclists a favor by letting us use "their" roads.
No doubt, he didn't have a clue. Next time, be prepared to offer a proper education.
Just copy your state laws into a word document, use a smaller font, space things so they are readable, but fit on a small card, and print away.
