Except that there are numerous examples of solar-powered vehicles that
*have* demonstrated substantial range at highway speeds.
There is no way it gets even 20 miles per kWh under anything but perfect
conditions and slow speeds.
Efficiency numbers in this range have been independently measured and
confirmed many times.
It is so light because it has almost no crash protection.
The Solectria Sunrise is a 4-passenger sedan with a demonstrated
efficiency of 40 wh/mile in several Tour de Sol races. These were done
on standard roads at posted speeds. It was also crash tested, and passed.
Some of Amory Lovins hypercar prototypes have achieved similar
efficiencies and crash test results.
Race cars are built with very light high strenth materials and
techniques. People have survived amazing crashes at very high speeds
with these designs.
