I'm more concerned about the Model X, myself. An SUV that can't be used with a roof rack doesn't exactly strike me as something that will set its market sector on fire.
I think you misunderstand who the average SUV buyer is. Most people never use an SUV to it's potential. That includes the roof racks. They basically replaced minivans.
I agree with you in the general case, but the Model X isn't targeted at the "average" SUV buyer. They need to appeal to younger, more active buyers -- people who are more likely than most SUV owners to hit the bike trails or ski slopes. We'll see, I guess.
They will have a solution to the roof rack problem. No one knows what it is, but they've been asked about it enough, and are aware that they will need a solution. What that solution will be is less clear, but there are plenty of possible solutions.
