Things I learned, a little griping (kinda long)

I ride the white line as much as possible... as far to the right as I can get.

That's been gone over pretty thoroughly in the other thread... but there's your problem. When there's no room for a car to pass you safely while sharing the lane with you, claim the lane so cars don't try to share.

Also, you need to ride far enough to the left that you won't run over gratings, and that if you encounter a pothole or debris in your line of travel, you'll be able to swerve right to miss it, not left into traffic.
