It sounds more like you are trying to play silly buggers than to be serious.

Cars - on average - are only used about 5% of the day when people are driving them. At other times, they are sitting mostly idle.

Obviously, if you are driving 12 hrs a day every day, then this does not work for you.

However, with EV batteries providing 50kWh to 100kWh in storage, some of that storage cold be tapped into to support the grid.

You would not completely drain all charge from the car battery, but drivers could easily set limits as to how much of their battery charge they might be willing to sell back into the grid. If they want to go on a long trip the next day, they turn off all V2G trading. This is all software driven and easy to implement

Now, if you have a 100kWh battery in your EV and you know your daily commute of 50km uses about 10kWh (roughly speaking), that allows you to sell perhaps 80kWh back to the grid (leaving you a 10kWh safety buffer).

Yes, you could just buy a stand alone battery for your house, but that is extra money you would need to spend, while you already have the EV.

With zero incremental cost, you could be earning money by selling electricity to the grid during peak demand and charge at off-peak rate (or for "free" from your own rooftop solar).

All these options become available as more and more EVs are on the roads. The EVs therefore become the cart that is pulling the grid along, facilitating a faster rate of installation of cheap and clean renewable energy.

You like to make many assumptions to suit your storyline, PP.
