I have an electricity contract with dynamic pricing that changes every hour based on the day-ahead electricity market for Belgium. I know what the prices for the next day will be around 13h10. I charge the car whenever the prices are lowest: around noon in the sunny months, at night during winter, preferably weekends. I save around 25% of my electricity bill like this. (More in summer, less in winter.)

So it's already possible to incentivize people correctly with price signals, at least in some regions of the world. But people are not yet familiar with this. I guess that will change as the pricing between dynamic and traditional contracts keeps diverging. With a traditional contract, you are essentially paying the average evening peak price all the time. With a dynamic contract, you get access to the cheaper and even negative rates.
