Electric motors also require far less maintenance and have far fewer ways they can break down. Oh, and if you live in a cold climate, you can warm it up in the garage without killing yourself.

And actually, if we reach a point where a solar roof and battery are the norm, and basically every vehicle on the road is an EV, civilization collapse becomes that much more unlikely. There's no longer a domino effect of the grid going down, pumps and refineries stopping, supply chains collapsing, and technology ceasing to function. Disruptions would be far more localized and their impact would be drastically reduced.

Isn't that one of the things many Americans want? To be self-sustaining and to not rely on others for their energy? Or am I getting this wrong? (silly european here)

A good friend of mine uses very little energy (just a smol fridge, a router, a smol TV and a phone charger) and he can actually get by easily with his solar panels up top and some batteries he got.

He barely has to purchase any energy anymore, sometimes even in winter.
