I think widespread blackouts are inevitable. The experience with the Texas blackouts shows that not only will people lose electric power, but also lose their water supply and raw sewage will soon be flooding waterways. People will suffer and yes die as a result of the blackouts. Of course all EVs will be stranded, however gas pumps will also be down. It will be interesting how the climate change cultists will respond to the misery and significant deaths.
Not our EV, but we're in a weird situation where both solar and EV work well in our climate and for our driving and power consumption habits. It's not for everybody, and I definitely recommend not jumping into it before doing a deep dive in your situation. But if it turns that it'll work for you as well as it does for us, I can tell you it's a secure feeling to have 80% of your power supplied by your own power for your all-electric home, including charging your EV (obviously for local driving, and on trips our solar charges it for only the first 250 miles). In a long-term grid situation we'd have to scale back some of our power consumption habits (i.e. on cloudy days no getting in the hot tub, no going out joy riding just to get out of the house, etc).
