Battery tech doesn't have to get 10 times better to make the ICE car obsolete. I'd say 2-3x, with faster charging times. When that happens (and it will) there will be almost no reason to own a fuel burner.
My favourite energy storage system is water, although it won't work in all areas. It works by using excess solar generated power to pump water uphill, at night it drains down and runs generators. With some creativity the system can be integrated into the surroundings so you'll hardly know it exists. I dislike wind farms, a lot. Battery farms seem to work very well and are modular so repairs and downtimes are not an issue.
