Every car I have driven in over the last 10 years has an adjustable shoulder strap for the front seat belts. This avoids the belt from cutting into your neck. The Model X has adjustment and I presume the Model 3 will too. Why not the Model S? Tesla needs to have adjustment as I call the seat belt a "chaffing strap." We are in the 21st century and there are some things we take for granted even in the compact econobox segment let alone in a high-end car like the Model S.
