Sorry Bob, let me clarify my point with an outside example:
 
100 years ago Nikola Tesla developed a method of trasmitting AC power
wirelessly. His prototype stages were successful, but he was unable to
complete his work and brings his ideas to society because of his investors
did not approve of his ideas on passing around free energy. The project
fizzled because it was not commercially feasible at that time. Now,
companies are starting to pick up on that technology because of the
emergence of small consumer electronics that could be recharged wirelessly
(computer mice, cellphones), and even MIT is proud to light up lightbulbs
wirelessly, using a 100year old method. 
 
The same goes with the cars- the development of the EV1 was critical for the
electric car because it was a "published" list of trial and error- it may
have sucked, but everyone is smarter because of it. The product was not
marketable to the world at that time, nor was it a very good product.
Another example is the 1960's Amphicar- if they really wanted to, they would
have been able to improve on that concept and make a well- designed, quality
product. One proven fact about progress is that it takes time, and most of
the time is spent in trial and error.


>Regenerative braking with DC is much more complicated. 
I don't doubt that- based on what I know about AC &DC, I can see why most
electric systems are AC. 
 
Personally, I'd love to have an electric vehicle. I don't drive over 200
mile a day, and would enjoy not having coolant, oil, exhaust, or fuel
systems in the car. I just hope for the day when EV's perform well and
aren't just damn ugly to look at.
