Definitely M40/A34 for me. In fact, you could offer up two further potential freeflow right turns on M40 Junctions, J10 A43, and J15 A46.

M6/A556 ought to have a freeflow right turn to. Been a few years since I've been up there and I've only just noticed they've hamburgered it. For anyone who uses that route regularly, does it help significantly at all? I have to say I've always found it a little crazy that there is this missing motorway link between the M6 northbound and M56 eastbound. Obviously since the upgrade to the offline D2 A556 the situation is vastly improved (and they did a good job with the M56 junction imo).....thinking back it was a ludicrous situation that traffic from the south had to use Chester Road to access Manchester, it was never good or safe enough for the amount of traffic it harboured.

At least at the east roundabout, the only traffic you'd ever have to give way to would be traffic doing a 630° or 720° loop of the roundabout – because entry slips are one way and there's no exit slip, not even the U-turn movement conflicts. This is not a movement anyone would use intentionally.

At the west roundabout, there's a potential conflict with traffic using the junction to reverse direction on the motorway (i.e. the movement from M42 northbound to M42 southbound), but that's also likely to be a basically unused movement (and would probably be quite dangerous in practice because everyone will assume nobody is taking it.)

The entire junction complex, covering M1 J21, the junction with the Outer Ring Road, the two horrible signalised roundabout monstrosities on Narborough Road, and the various other signalised accessories leading to business parks and retail parks, would ideally be razed to the ground with a targeted bombing campaign and replaced with something else altogether. It's an absolute failure of land use and transport planning.
Agreed! The very short merge onto the M1N (right lane - I know the left becomes an extra lane) is just the cherry on top.
