A little battery would not last 200 miles. Big batteries are only needed if big journeys between recharge are wanted, without having to stop for 4 hours en route for a recharge. <Try doing that going more than 200 miles in one direction.

Do you have any idea how heavy those batteries are?
> Yes.

You have missed the reasons for using little batteries.

<You'd also need at least 6' of clearance on both sides of the car - not the usual garage. > A battery recharge and swap station would be a lot different from a petrol and diesel dispenser station. Yes, not the usual garage.

I have swapped batteries in cars by hand. But since the industrial revolution, we have machinery for doing heavier jobs. I used to drive fork lifts. There are probably better mechanism these days and engineers can design machinery to lift and move things. <Wonder what the capital cost of a gantry crane in every garage will be.
Most folks struggle to lift a standard 12v car battery.
> A "gantry crane" would be comparable with a little battery-powered fork lift in price. The capital cost would be minor in the overall cost of a battery swap station.

<Sounds once again like elitists only need apply.> Seems as though you have not got the idea.
