At this stage several cars travelling at 110 km/h including a large truck had to slow to avoid my vehicle which was unable to maintain a speed above 70 kmh. An extremely dangerous situation, I had my wife and 16 month old in the vehicle !
Car was placed in Drive again from Neutral with car rolling at approx 70 km/h and a second attempt at trying to get to highway speed caused the vehicle to go to Neutral again, it was observed at this time that vehicle Tacho went from 4000 rpm to 0 then back to idle speed...previously had a problem with the car changing with a "Thud" and searching for gears at the exact same place !!! It does not occur in normal driving conditions arund town (max 80 kmh on expressway)..... ... It would appear the engine is cutting out and the car is going to Neutral... It's extremely dangerous when this occurs... I am writing a letter to BMW to detail the situation and my request for a proactive diagnostic approach at my next service appointment...rather than everything looks ok , no check control messages stored & the usual warranty blurb.... Any ideas or comments welcomed.. maybe a software update woudl fix (or at least should be one of the first things they do? ) ?

Is your shifter actually MOVING to neutral?
You state you had to shift it to Drive? How did it get to neutral?
Is this "shifted to neutral" just mean "it wasn't driving the car" or 'the engine was not powering the wheels"??
The 'couldn't replicate' is BS. Ask them to pull all engine and transmission troube codes, including all historical codes.. AND GIVE YOU EVERY SINGLE DOCUMENT. Insist on a complete diagnostic of the shifting and transmission system.
