What are you? Crazy?
He's supposed to give me at LEAST 3 feet, and he was travelling at about 40mph.
I think you need to get perspective on those pics, that camera is mounted on the right side of my head tube, so the left edge of handlebars is about 10 inches from this azzhat's rearview mirror.
Ask yourself this... would he have passed a mailman that close, that fast?
What was the speed limit on that highway? Because there is no way you were going more than 25 mph for any good stretch of time and I'm betting that highway's speed limit is a lot higher than that. So in your world, he or anyone else should just cruise along at 18 mph as to not screw up you and your riding. You said you are a vehicular cyclist because you consider yourself a vehicle. Good for you. Then either learn to peddle at 40 mph or stick to the bike lane.
Just remember you can't win in a collision, nomatter how right you are. Even yielding can be deadly. A cyclist riding near a job I was working at, moved over, lost control on the edge of the asphalt, and fell in front of the trailer wheels of a loaded semi. He was a very experienced rider, with top notch equipment.
