The only problem is that these assumptions rely on non-existent infrastructure which costs a ton of money to build and maintain. The overwhelming majority of parking spots don't offer EV charging, so people would have to charge their car at night when energy is expensive.

Even if we did have EV charging available everywhere, excess of energy during times of peak production is the reason why energy might be cheap or free. As soon as you actually start utilizing that excess, the prices will stabilize around the average market rate.
