The blogger might be an ignorant, but the OP post doesn't reassure me. If I go in a 5 months travel doing consulting abroad, and I'm living alone; who guarantee that my car is being constantly put on the charger? There are many cases (plug dysfunction, electric problem...) and $40K is not a trivial amount.
I'm sure a reliable person could be located to look in on such a parked vehicle once or twice. Especially if they are offered a couple hundred a pop to do it.
If such batteries become prevalent, I would think that monitored charging garages and bonded maintenance services will spring up.
Another error on the part of the blogger is the claim that if the cars discharge fully, the battery
packs will be damaged. This is blatantly false. The battery management system of the Tesla
Roadster keeps the battery from being discharged to a damagingly low state of charge under normal
driving conditions. It's true that a full discharge to zero percent state of charge can potentially be
damaging to a battery. However the battery management system of the Roadster won't allow the
car to reach that low level of charge.
