Why is the MX taking so long when so much of the complicated stuff will overlap with the MS? It is really only a different body and interior. OK maybe the MS is consuming more time and money and effort than imagined but.............. I'm sure Tesla want the MX to be 'perfect' compared to the MS which had a lot of sympathetic early adopters (and Tesla fanboys..!) and could afford perfection 'on the run'. Maybe, just maybe, the falcon doors are proving seriously tricky with the potential for bad press and reports and poor reliability in the real world. Tesla may decide to make the late call to go with normal rear doors - perhaps much larger than normal (and powered to open and close) and spin the 'bad' publicity somehow. What do you all reckon to this 'flight of fancy'.....?
