>> If you leave your bubble a little you'll learn a lot
I'm not in that much of a bubble. I'm currently working at a company that makes 60-120kW DC fast chargers. I've talked to many people who actually own EVs. I get that the "home backup" use case is a bonus, but it's not a key selling point and it costs more. Also, the utilities want to use your car for "grid support" by making it bi-directional which is different than using your car as a backup when the power goes out. For backup you need the ability to disconnect the house from the grid while powering it from the car, and that's additional cost that people will balk at.
