Yes, the car pool would have several cars. While one is charging 
another could be driven. If they are all out, excess solar power 
could be fed into the grid.

Yes, the cost needs to come down a bit. But $30,000 may not be 
unreasonable if you have several cars in a pool. The ANU has made 
some solar breakthroughs. I have suggested that these might be used 
in India, where the power supply is unreliable. You could use the car 
batteries as a backup power supply for a building

If the fuel supply tapers off over a decade or so (or the price gets 
progressively higher), everyone can gradually adjust by first buying 
a more efficient petrol car and then an electric one (or use a bus).

Yes, but it is still within the capabilities of a backyard mechanic 
to convert a petrol car to batter electric operation. Granted, Shaun 
Williams is smarter than the average backyard mechanic, but he did 
literally take the engine out of a car and put in an electric motor 
and batteries, then had it registered 

Just to make this relevant to Link, the interesting part I think is 
how to use the Internet to provide an infrastructure for such vehicles.
