I recently test drove a 6 seat Model X. I was disappointed that the center row seats didn't have flip down armrests like most minivan seats have. An arm rest would make the seat more comfortable for long trips, plus feel more secure during cornering. I could see an asleep kid falling over. I prefer the 6 seat configuration over the 7 because the 3rd row doesn't feel as claustrophobic. Elon: please put flip down armrests on the middle row seats. Would like them in front row too, because arm rest is always in the right location no matter how far up or back the seat is.
