I'm ashamed to say that Chevening once caught me out, long ago, when travelling anticlockwise. Looking at the signage now on streetview, it's actually clear enough. A more graphic additional illustration of the layout would help further.jackal wrote: ↑Tue Jul 19, 2022 00:06 We have some quite bad cases in the UK of wrong side merges and diverges, and while more lanes helps in some respects, it doesn't in others. For instance, adding lanes to the M25 anticlockwise through Chevening with a wider approach would mean that trucks heading for the A21 would have to move across several lanes to get to their exit, disrupting the M25 flow. I'm not fanatically anti-offside exits, but a nearside exit for a much lower volume route is inherently better in my view as it keeps slow traffic out of fast lanes.
The problem of finding oneself in slow traffic on the right side of the carriageway is real, but in the case of Chevening there's quite a distance to achieve two or three lane hops before the next exit, especially when travelling clockwise.
As I've often remarked in other contexts, I suppose AU's and USA's laissez-faire lane discipline reduces this problem. (Note, I don't hold AU's approach to lane selection either better or worse than the UK's stricter interpretation - just different. They both work, as long as you know what's expected. And here in AU we do have occasional advisory signs reading "keep left unless overtaking").
