About ecology and Prius batteries:

When the 2003 was rolled out, Toyota bought a "Classic" Prius taxi from 
it's owner in Vancouver, BC.  The car had about 240,000 city miles on 
it.  Original battery still working fine.

They gave him a new Prius (which he promptly painted and put into 

Toyota shipped the old Prius to Japan for disassembly and inspection.

The hood (bonnet) and rear hatch (boot) are made of aluminum to reduce 
weight and conserve fuel.  The Coefficient of Drag is one of the lowest 
in the world for any production care.

Every time you let off on the accellerator or coast down a hill, it 
regenerates voltage.  This also helps with braking.  No one knows for 
sure how long the brakes last on the newest model.

It doesn't really seriously start "pushing air" until about 62 MPH (my 
favorite cruising speed).

Finally, it is a "PZEV" rated (Partial Zero Emissions Vehicle".

So, for the money and given the state of the industry, I had no problem 
buying one.

good vehicle. About 5 or 6 litres per 100km and that is city commuting. 
Also extremely responsive with the power being available at
low revolutions compared to petrol driven types. Bicycles are great, 
but not the whole answer nor suitable for every use.

I agree with all of this.  The latest clean-burning turbo diesels are 
impressive from many points of view.
