Re: For inner cities/battery charge
There'll need to be
some smart logic a lot of investment in cars lying idle most of the day in the system so that maximum numbers of vehicles are available and charged at times of peak demand, but this is scarcely conceptually difficult.
That's assuming "maximum numbers" means "enough to meet demand". A private motorist might be prepared to invest in a car that lies idle most of the time because the journeys they make in it are important enough to them to justify that. An investor is going to want RoI over a short enough period to make it worth while.
