alt Hacker News> That doesn't mean electric cars shouldn't be considered as power backup, or that buying a nice electric car vs a nice gas car doesn't come with the added benefit of "Don't need a 10k generator anymore".
From redundancy perspective, a genset + car is hands down a better combo. A functional ICE car is cheaper and goes everywhere without any trip planning around charging stations, which is another plus.

I mean presenting one set of tradeoffs just shows that there are tradeoffs.
If you're looking at two $55,000 cars, and one has power interconnect and one does not, it's not like adding a $1000-$10,000 generator on top is somehow immediately better unless you're adding in factors that make it better (like buying a cheaper car). There's 3 or 4 superchargers within a few miles of my house, and every time I've lost power I could easily go charge my car so I never worried about that.
Not everyone lives in that situation or has the same "one or two days without local power but chargers still work" threat model. It just so happens that's been the biggest actual, real, problem that my car could have fixed for me.
If cost is your only factor yes. But the vast majority of people pick cars they like, and EV's are great. No need to dog on them needlessly. The trip planning thing is super overblown. Now 2 years into my first EV, going to a charger that's not my house _at all_ is quite rare - couple times a year; even when I travel Portland to Seattle, I don't have to stop on the way such that outside Olympia, I don't even know where the charge stations are. And that's the worst it'll ever be.
