I've been going downhill at a reasonable clip and taking the center of the lane (because of speed and the hazards of card doors opening up suddenly) and had cars behind me be so impatient to pass me that they'll forget to check for oncoming traffic and nearly get into head on collisions with other cars. I also started pulling fully into the lane because even though I'm travelling at speed downhill I've had cars pass me, with about an inch to spare when there was oncoming traffic and they were nearly pulling into the other lane -- I've had to take the tactic to force them to choose between flat out murdering me or else getting into a head on collision if there's oncoming traffic. Another time there was construction with cones out and I went inside most of the cones and let cars by, but had to merge into traffic around a cone where the actual construction was happening -- and a car decided they couldn't be slowed down for a second by a bike in front of them and they passed me and ate a traffic cone and dragged it under their car for 2 blocks.

Some people just completely lose it when they have a bike in front of them that is going to slow them down for even a second or two. I don't know if its rage or stupidity, but they get really, really dumb.

I can't wait until manual driving on freeways and in major cities is just banned and everyone has to have their cars on computer control. All the road rage goes away, all the inattention, all the derp would just go away, and traffic would move faster, and all the headgames would be gone -- replace it all with google algorithms that know how to pass a bike safely.
