Recently took delivery of my Model S. Love the driving. Perfect. BUT... the absence of reasonable storage space for small items like parking passes, sunglasses, meds, etc is a real problem. The glove box is small and hard to reach from the driver's side. There needs to be a center storage console. All cars I've owned for the last 20 years have had that. Generally with two compartments, a shallow covered tray on top for small items, and a deeper compartment for larger items like gloves, kleenex, etc.
The floor tray between the driver's and passenger's feet is silly. Putting things in it guarantees they'll fly about on sudden stops, and trashes the otherwise clean look of the interior.
Will Tesla or an aftermarket manufacturer please come out with a center console I can install with velcro? It will unfortunately be expensive because it will need to bring the power and USB adapters through the console to a new location. But I'll buy one as soon as it's out!
And yes, as others have commented, the rear seats need cup-holders. This is simply fact in America today. It's the way we travel.
