Why Are Cyclists So Hated...

I gathered recently that buses are somehow not subject to them...

I was really just illustrating that, like asls, yellow hatching isn't actually that simple. :)

Oh, I thought you were joking ...

Isn't the actual definition of the cross hatched box, your exit must be clear to enter (not the same as you must not stop) so if turning right, your exit could be clear, but you've still got to wait for the contraflow to let you through. I thought buses were subject to the same rule (I have seen some buses follow it) but I thought they just ignored it or had some argument that saved them from it!
