PHYSIX OBSERVATION

Tesla is pushing vehicle-to-home power down from its pickup to its volume sellers. The direction is right, but the bar is not low: you need a Powerwall 3, and older owners are shut out for lack of an inverter. This looks more like a hook to sell the energy-storage ecosystem than a broadly accessible feature. For users, two extra days of power during an outage has real value, but whether it is worth paying for depends on tallying up the full system cost first.
