But the 'literal' interpretation of the Law is the only definite thing we have to go on here, if that's what you mean by "literalist". Everything else is open to interpretation and subjective arguments.It's a bit of an immature view banging on about things in such a literalist mode.
If you want my subjective approach, fine. I have only one ASL in my area that I have total acquaintance with, seeing as it's on my commute. The feeder lane is on the left, so this tends to encourage the cyclist to approach on the nearside, filtering as necessary, and then position themselves well to the left in the ASL box, inviting the risk of the 'left hook' should they be a bit slow on the off. Motorists often don't indicate there - they don't see need, seeing as the only other road user in sight is 'only' a cyclist. So - I don't like the layout.
But others may - subjectively - see it in a different light.
As it happens, if I'm first there, I tend to take a central position in the 'box': this means ignoring the feeder lane and technically 'breaking the law'. But safer.
