The almighty fly by like Maverick in Top Gun. Except it is a big car instead of an F-14 Tomcat, and me on a bike instead of a tower.
After a few of those, I REALLY take my lane now. I've driven by cyclists before, it doesn't take but a few seconds to wait for a clear opening to pass. Apparently, those seconds are more valuable than my safety to some...
And let us not forget the dive bomber. They fly around you, then slam on their brakes, causing you to slam on yours, in order to make a right hand turn directly in front of you. Patience is a lost art these days, it would seem.
