I just took delivery of a new Model X today. I had previously had a 2016 Model X and loved it. The issue I am having is that I am 6'7" and the drivers seat in the name X is really narrow. The portion that is supposed to keep you in the seat just diggs into my leg. Does anyone know if there is a way to alter the plastic in the seat or is there is another alteration or modification to make a big guy fit?
