PlayStation South Eastern High-speed - Ai Javelin Drivers

Hello, I had a problem yesterday when I took over from an AI driver of a Javelin at Stratford International Station, in ended up that the driver that had brought it into St. Pancras International Station hadn't shut down the cab at that end and so both end's were fighting against each other for control of the train and so when I was braking for Ebbsfleet International Station I didn't have any brakes to speak of and overshot the station and passed the platform starting signal. Then tried to reverse but that's when I found out that the other cab wasn't shut down as the master key was in, reverser was in reverse so ended up having to shut down my end and use the other end to get back into the station but after loading passengers I couldn't continue as the Signaller said that the train was on a different/wrong path.

It would be useful if the Javelin AI drivers shut down their cabs.
