Very good and comnplete presentation, but short... Allows interested persons to look for more informations on internet, or in other videos... Quite everything is partially shown, but not illustrated nor explained... But this short and accurate presentation can interest persons who do not have much time, to see what is available, for half of the price of a similar, but less effective car... This X9 increases the efficiency of vehiles and transform this van in a family limousine, and a sport car when requested, but corresponding to future standards of autonomous taxi : you do not have to be your own driver, now you will be able, in this car, to be a passenger!
