Does anyone know how the 2nd and 3rd row seat space of the Model X compares with the Model S? I like how much room the backseat passengers have in the S but all the pictures and videos of the Model X looks like there is less space. I personally don't feel very comfortable having to place my feet under the seat in front of me in order to sit in a car seat and I know many 3rd row seats are like this. I'm hoping the Model X will have sufficient room but I'm wondering if anyone has sat in the prototype and if so, how much room was in the backseats and also in the 3rd row seats?
