This comes from sliding in over the seat in lieu of getting in with your butt off the seat and then dropping into the seat. The Tesla fake leather tends to stay tighter with less wrinkles overall compared to leather. It is about the technique entering the car...looking at the wrinkles in the passenger seat leather. Tesla really needs to work on this. Our Lexus was 10 years old when we sold it and its leather was still more tight than that.
