Unless you really want to have seven seats, I think that to have six seats is the optimal and most comfortable configuration. - For long trips, the central seat of the second row is not really the best place to travel. - Also, if your two second row seats have baby seats installed, you still have two additional, easy to access, regular seats on the back. (Otherwise, with seven seats, the only access would be to move forward the the second row seats, and then passing behind the second row seats.) - The six seats configuration reminds me in particular the Mercedes-Benz R-Class with two captain chairs in the middle row and two additional back seats. Since the Tesla X second row seats cannot be folded, I assume that the simplest way to access the third row would be: - instead of moving the second row toward the front seat, and then passing behind the (unfolded) second row seat, - it would be simpler to enter from the second row and then to reach to the third row using the gap left between the two second row seats? If you are accessing the third row by passing in front of the second row seats, instead of passing behind them, I wonder if regular doors with hinges, instead of falcon doors, would have been simpler? May be, the Tesla 3 "Y" will offer a six seats configuration, with two hinges doors, to save both on weight and cost, because I think that falcon doors would be really justified? So what your advise from choosing a six seats versus a seven seats configuration? And how do you recommend accessing the third row seats?
