Super long-term kernel support - fuel availability for 20-year-old cars

Tesla built and demonstrated a machine that could replace the battery pack in one of their vehicles faster than you could refuel some high-end car. I’m sure there are YouTube videos of the press demonstration available. Elon Musk was talking about installing such machines around the country alongside their super chargers, but I think they must have dropped the idea since I haven’t heard anything about it recently.

I guess the energy capacity of a gas pump nozzle is somewhat analogous to the bandwidth of a truck full of hard drives driving down a highway — wires aren’t always the fastest way to transport energy/data.
