Peak energy prices are approximately double that of off-peak.
For example, if 50% of a standard Tesla 3 battery could be reserved for this, 31kWh, you could make about $8 per day, or $2,900/year, plus be contributing hugely to grid stability.
It could be as simple as setting cars to discharge back into the grid any remaining power from 4PM-8PM (depending on user preference), and charging from 11PM - 7AM.
It seems totally reasonable for regulators, grid operators, carmakers to collaborate and create standards and mechanisms for car owners to charge and discharge based on their typical driving needs and live pricing.
Look at the enthusiasm for GPU mining - people will flock to getting their cars to do this.
If people can make serious money from the vehicles just from charging/discharging, there's also a big motivation to design batteries with longer lifecycles.

Perhaps blowing bubbles in the ocean dead zones [1] would be a productive use of excess power? The bubblers would be turned on and off to bleed off extra electrons from the grid.

From the cnbc submission:

If the next two winters are excessively cold [2], a real leader might arise to tell the anti-nuclear activists, 'you mean well, but we do actually need these thing for the next 20 years.' This leader would point out that the alternative is for all the Californians who are priced out of expensive electricity/natural gas to use coal from the Navajo Nation/etc to heat their homes [3].
