Nah, people want to wake up in the morning and know they can drive somewhere.

Requiring it is crazy.

In a hypothetical future where every single car participated, you probably wouldn't need to dedicate more than a few % capacity to still make an absolutely massive VPP

True. But a household battery can do that, using heavier+cheaper chemistry.

Leaving the car to do what a car does. Travelling by car takes a lot of energy.

To keep current lifestyle across the population I figure we'll need both.

28% of trips are under a mile, 52% under three, 64% under five, 79% under ten, 93% under twenty-five, and 98% under 50 miles.

Only 0.8% of the trips are over 100 miles!

That's cool. But how does the system match the draw down with your needs the next day? How can it possibly know?

Unless you make it voluntary, because you yourself know.

You can decide what level of charge to keep. Its is simple thing on the app. Or decide not to participate that day, again, a toggle on the app. Surely you'd know where you are going tomorrow?

You and I agree. It is the "requiring" that is crazy. Let people do what they want.
