You have to admit, the Model S cupholders (at least in the 2015 "model" year) in the arm rest are awkward, at best. I am tall and need a full arm rest and with the cupholders in use (and a passenger in the seat beside me) the arm rest is pretty cramped. A truck is about utility (and nowadays, comfort), so it's not unreasonable to expect Tesla to take advantage of the space available to put in some built in storage. That's not to say that Tesla couldn't design a removable center floor console that can be secured when in use and then easily removed when you need 3 people sitting in the front of the CT. Wouldn't that be the best of both worlds?
