I've read many articles in the AMA mag about lane splitting but cannot say that I ever thought the value in it outweighed the risks. Although if I lived in an area of heavier traffic I might think differently about it.
I try to ride my bike to work every day that the weather allows and when I don't have to pick up grandkids. I have, and am, trying to slow down when I ride, particularly in the early mornings (dark). I'm learning that when a hazard, or hazardous situation presents itself, I want to have plenty of time, and room/space to react to it.
I read street and road intersections closely, especially if they're busy intersections.
