Solving the max power problem by duplicating every EV battery so there is one stationary one and one in the car is vastly cheaper and actually physically possible. The net average power required in any given week is well under 600GW even assuming average efficiency is around 750Wh/km (1/4th of a tesla). But that said, fewer and smaller cars is a much better solution. Most car trips are unnecessary if you have reasonable infrastructure and don't make cornerstores illegal. 25mph LEVs and NEVs can serve most of the rest and can be powered purely on the sunlight that lands directly on them where 90% of people live. Trucking is a major issue if you don't want to spend those trillions on functioning rail instead, but no trucking company is going to pay $1/kWh just so there can be terawatts of idling nuclear capacity. They'd just build their own renewable+battery depots at $0.2/kWh.
