Energy price volatility will probably increase because natural sources are more volatile and other sources have spin up / down cycles. A car battery is like 3-4 days of continuous house usage. The car battery being used to top off the top 10% in short term pricing for energy would give a very nice ROI I expect. The rest is software? Don’t overcharge, don’t go under the limit I set for continuous availability as a mode of transport. And that’s all within reach in front of the meter, thus under my ownership. Heck, without self driving becoming common a family might even have 2 EVs on the driveway, giving a week of off grid potential.

Come to think of it - a harder part is how super local the grid is and energy pricing should become. In my somewhat affluent neighborhood in high summer the voltage rises too high and the supply of solar falls. And tragedy of the commons - we are still installing solar because it’s massively incentivized (2 years before investment returns itself). To solve this with EVs requires very granular prices. There might be clouds 50 km away. But again, those are software solvable issues. (I’m not holding my breath. It’s like IoT-superplus.)
