This sounds like my 14 year old Avalanche with 160k miles on it. It's still functional as a great backup/utility/beater truck. And that's the plan for my R1S in 15 years.The suspension and brakes will be rusty. The body panels, seats and trim will be scratched and dented. The interior will stink from 10 years of fast food drippings and the perfume that you have added to try to cover it up. The computer will feel slow as molasses. The LTE cell reception will have gone dark. The state of CCS charging will be like chademo is now (slow, and only one stall if any). The safety features would be insufficient to be legally sold as a new vehicle. And all sorts of small things will have broken that weren't worth fixing post-warranty.
Batteries aren't being designed to be repairable. There are good reasons they aren't doing it, but it does make it so small cell failures where you'd otherwise just be able to swap a good cell in can kill a pack's usability.These guys got it figured out.
