I don't really get the point. What if they'd have put the R&D money into an XL0.95, a super-super-efficient XL1 that uses 5% less energy?
Diminishing returns, I know. Wonder how much they could cut material cost by designing the car for a single person, instead of two. That should bring the retail price down to a positively reasonable $95,000. But really. We need this technology to enter mass production sooner than later so the costs really come down.
I'm still waiting for a no-compromise Volt...
