It seems to be the only fully operational Tesla Model "X" yet in existence as we don't have any other media source who has spotted or covered this model before. Also, I personally think other car Mfg. need to support as Tesla cannot be the only manufacturer lobbying for side cameras instead of mirrors. The camera with sensors, and a rock solid software will ultimately do a superior job with blind spots than the mirrors.
