thats the thing, while I stand by my earlier comments for the situation in that photo, I realize that there are situations that one has to behave differently.
I have been in some situations where I had to be more aggressive with lane taking, but when there is a high speed differential, it can be tricky.
internet forum talk is tricky, we tend to have formed scenarios in our mind when responding, but I still basically rely on pretty much 40+ years of riding on two wheels motorcycle wise, and longer bike riding since I was a kid---to I go with my instincts and common sense about what to do for every specific situation.
I realize that its impossible to give a absolutely true black and white answer, as situations can be so different.
