The Model X has been delayed several times. Altogether probably at least a year an a half's worth of delays. Who's becoming impatient with Tesla with regards to the X. I believe the D was all the goodies that were supposed to be in the X. But Tesla came out with the D to Deflect, Delay, & Divert attention away for the problems they are having with the sealing the Falcon Wings Doors properly. I like the Falcon Wing Doors, but If it means waiting another 6 months for the first one to hit the road. It really makes me say Tesla just give me a dam SUV with normal doors. I mean I kinda wanted S drivers to envy my X but now that have all our goodies. I reserved the first day and I had a S reservation for years before that. I'm really starting to get annoyed with the lack of progress on the X. I mean the first X's were scheduled to be on the road in December. Now the X won't be shown until the Detroit auto show in mid January. WTF??
