    I’ve noticed AP doesn’t undertake unless you press the throttle and it will go ahead and do it. It does however sometimes decide to undertake at what appears to be random. Does anyone know the methodology?

    Mine undertakes, doesn't give an f about the law. Never notice it refuse to undertake, it just goes for it.

    My friend has a Golf R that refuses to undertake at all.

    Same with my Audi S3 with active cruise. It’s the only sensible bit of the car, everything else about it seems to be the same level of Golf R borderline unhinged, but with quilted leather and dialled back just a tad on the ASBO scale.

    It, at least FSD, will not undertake if you are on the inside lane.

    Gonna test mine again but have been on the motorway before on the inside lane and I'm sure it did undertake.

    It's not always an offence to undertake in the left lane but weaving in and out of traffic is.

    Autopilot has avoided undertaking when I've used it.

    As per the excerpt from the manual (always worth a read ;)) in post #7 the car will undertake at speeds up to 50 mph. This is to reflect the flows of heavy traffic where the speed will vary within the lane. A little tap of the go pedal will over ride and break the link with the car in the adjacent lane (which is highlighted as the car whose speed is being tracked).
