Cycle paths are optional here, and I very regularly opt out of driving on them because they are in a constant state of disarray, had snow and glass shoved on them, are too close to parking cars or end abruptly, forcing me to merge into traffic. So, being a vehicle, I drive on the street. I drive on the middle of the street, because (1) bicycles come with two (bi) wheels and naturally oscillate (2) street conditions very frequently make it necessary to use space to my left or right and (3) to make it clear that you can not overtake me in the same lane.
Car drivers regularly think this is an invitation to overtake me extremely closely, basically touching. They value my life, really any life, so little compared to the nonexistent time or speed benefit they would get from overtaking me. They think they are supremely in control of a large four ton object driving at 30 mph when they couldn't park it to an inch to save their life. They think I have done them wrong, and are now trying to get back at me; it's a game to them!
I don't know what it is that makes people lose all compassion or basic rational understanding of risks and dangers once they get into a car.
