I do not think there is much to lubricate in a Model S. The drivetrain uses sealed bearings. No gearbox, clutch, automatic transmission. Just motor, single speed BorgWarner 2:1 fixed reduction gear. HVAC may need occasional refill of the refrigerant, but that is every few years. Pot holes will determine of alignment is needed. Brakes every 100,000+ miles may be with regenerative braking. LEDs last the life of the car. They could substitute some of the filament bulbs in the license lights and the beams with LEDs. That is minor.
Of course, ICE cars these days need very little maintenance. Something like Toyota, Lexus, etc hardly ever break down.
In theory no, in reality It's possible, but only Tesla knows. If you go to KBB and check the TCO for 5 years Nissan Leaf is High compared to other in my opinion comparables but I am a short (Mostly and happy about it today)
It could be a income generating method of paying for the centers. $600 a year.
i'd invite you to reconsider you opinion. as for my leaf experience, 27k miles and 1 scheduled maintenance for post-delivery inspection. no oil change, no brakes, not even tires with good wear remaining.
Since the software upgrades are done via the home wireless internet, what is needing servicing every 12,500 miles? My gasoline combustion engine oil is changed every 7500 miles, so a 5,000 mile service improvement does not sound like that much of an improvement for a non-combustion engine.
