Add more batteries: http://calcars.org/priusplus.html !
Put some lexan over that solar panel.

And that solves the insurance and cost/benefit issues how?

No insurance available for experimental projects !
Experimental stuff usually does not have a cost / benefit analysis
done until the end of the project. If we weighed cost/benefit on
everything, no one would have kids !
Besides that, you wanted to drive in to town on electric alone.
No cost was mentioned. The solar panel and extra batteries get
you there as long as you stay below 39 mph.
