Does anybody know if those doors have cup-holders? Parents of small children might get a little surprise when they open up those doors if they do.

In any event, they seem more practical than regular doors and are certainly cooler than sliding doors.

That must have been a design tradeoff.

These are some pictures of the Model X, I have found. There are no "holes", only arm-rests. The black detail on the second picture must be the window control.
